            Fait partie de Jim Dufour
            One silent film of Mond Nickel mines in the Sudbury area. Film is divided up into the following sections by title cards (time each card appears in the film is noted before each title card caption); Part I 00:00 – The Mining and Smelting of Canadian Nickel, Mond Nickel Company, Coniston, Ontario, Canada 00:08– Nature’s Storehouse and the Company Mines 01:24– Diamond drilling to determine location and extent of ore body 02:01– A Typical Nickel Mine 02:12– Let us go down into the mine and see how Nickel Ore is obtained 02:57– We will follow the car through passages called “Drifts” far below the surface 04:14–The end of the drift. Drill runners preparing a blast to extend the drift to reach new work 05:24– With compressed air force and great noise the sharp edges cut into the ore while a stream of water pours through the hole to keep the drill cool 06:23- Dynamite handle with care 06:31– Fuses eight feet long burn four minutes. Detonating cap being placed on end of fuse 06:41– The cap is inserted in the charge of dynamite 07:02– Ten or twelve holes are made from four to ten feet deep in a surface of five square yards 07:21– One stick of dynamite is placed in each hole for every foot of depth, about 30 lbs. in all, the last stick in each hole has a fuse attached 08:30– We didn’t wait to see what happened, but this was the result 09:15– When main development drift is finished the ore above on each side is measured into sections called stopes, 100 feet wide, 100 feet high and as deep as the ore runs, leaving a pillar of solid ore 40 feet thick between the stopes as a brace 09:43– Each stope is mined as a unit – Sub drifts run from main development drift under each stope. Draw holes are run up at 45 degrees from the drift to develop the stope and draw out the ore 09:57– Each stope has several draw holes from twenty-five to thirty-five feet apart – a draw hole viewed from the drift 10:22– Let us follow the miner into the stope 10:42– Here a stoping gallery is made 8 feet high and full size of stope. The roof or hanging wall at the high side is cut horizontally and broken down forming a perpendicular face which is carried, blast after blast, the full length of the stope 11:02– These blasts are fired by electricity 11:17– Section after section layers eight feet thick are blasted from the roof and broken up on the floor. Lumps too big to be broken up with hammers are broken with a small dynamite blast. Blasting large lumps 12:16– One third of ore is removed, two thirds are left on floor to stand on in reaching the hanging wall when blasting down the next layer 12:33– This operation is repeated to within ten feet of the floor of the next level above. When all the draw holes are closed, the miners enter and leave by “rises” from the drifts above 12:50– Miners going up out of a stope through a rise. These rises serve also as auxiliary shafts in case of fire or closing of mine shaft 13:22– When all the ore in the stope is blasted down and broken up, the drawholes underneath are opened and the ore removed 14:39-This – the cheapest and safest method of Copper Nickel mining is followed in 90% of Mond Nickel Co. operations – 100,000 tons of ore are stored in this way at one time 14:59– Diagram of overhand stope mining method 15:23– In the underhand method of mining, one draw hole is made at 45 degrees through the stope – then a working gallery is made at the top of the stope. The ore is mined and blasted downward through the draw hole and removed at once. Scene in an underhand stope 15:55– In ever widening series of ledges like a great funnel this ore is mined and removed 16:09– Men with scaling ladders constantly inspect the walls of partially emptied stopes to remove dangerous loose pieces of ore 16:59– The skip may be loaded direct from cars on main drift – cars hold two tons – two cars fill the skip 17:44– It is not always convenient to load skips at each level. Ore may be passed down through storage pockets to a suitable loading level far below 18:09– The grating over the passage to lower level is called a grizzly and is for protection of men. This ore goes direct to loading pocket, a great bin cut 50 feet deep in the rock 18:26– From the main drift above loading level, ore is passed from cars through grizzly to loading bin 18:50– The ore is measured into skip loads weighing four tons. The skip weighs three tons 19:36– A waste dump on each level where rock is loaded direct into skip 19:55– Drills dull very quickly and must be taken up to be sharpened 20:20– Ladders as well as the skip run to the lowest level 20:31– Telephones furnish communication between the drifts and the offices above 20:59– The end of the shift. All aboard for daylight 22:11– Safety switch on operator’s bridge stops all motion instantly in case of accident or danger 22:33– Compensating balance of the two skips and cable 22:45– Skips carrying ore go direct to top of shaft house 23:20– On next floor below ore and rock is separated – both pass through crushers and are broken up 23:49– From crushers the waste rock goes direct to bins over railway cars. Ore goes through a revolving screen which sifts out the “fines” 24:13– On the picking belts, waste rock, low grade ore and high grade ore are separated 24:32– Waste rock, fines, low grade ore and high grade ore are being loaded into cars from bins 25:01– Let us inspect the equipment above ground before following the ore to the smelter 25:10– Power used throughout the mines, smelter and town sites is Hydro-Electric generated at the Company’s own development plants and transmitted over 72 miles of line. Wabagashik – the Company’s first power development 25:56– Seventy feet of head, developing 5,000 Horse Power 26:33– Two horizontal twin turbines develop 1250 H.P. each Part II 00:00– Nairn Falls, four miles from Wabagashik, capable of developing 7,200 Horse Power 00:45– Two single runner vertical turbines develop 2,400 H.P. each 01:12– The power lines – 44,000 volts leaving power house 01:42– At mines, power is transformed to 500 and 110 volts for service – Transformer station at mines 02:03– Three compressors supply 7,700 cubic feet of air per minute to pumps, air cranes, forges, skip brakes and 80 miner’s drills 02:44– Sharpening ore drills. Clearing water passage and retempering 03:35– The repair shops at the mine 03:48– The dynamite house is far removed from other buildings, only 24 hours supply kept on hand 04:09– Dynamite freezes at 40 degrees and must be thawed out 04:22– The store house and mine offices. A “shift” is checking in 04:32– A well equipped emergency hospital for first aid 04:47– The dry house. Hot air below – ventilation above – Clothes are dry when needed again 05:31– Homeward bound – clean and happy 05:49– At Levack mine connections with main line C.P.R. four miles distant is made over the Mond Nickel Co’s own right of way and equipment 06:10– “Old Reliable” the Mond Mine at Victoria, 3,000 feet deep – the deepest mine in Canada 06:52– Worthington Mine 07:06– Garson Mine has ten levels and is the greatest producer 08:01– Bruce Mine supplies 50 tons of quartz daily for smelting purposes, and pays its way by the Copper produced 08:22– The ore from all the mines is brought to Coniston, Ont. for smelting 09:21– All material is brought into smelter and moved from process to process in car load lots over standard gauge in Railway or the Company’s own cars by the Company’s own motive power. Ore train arriving from the Mines 10:01– All material entering smelter is weighed and taken to storage bins at smelter or to storage yard. High grade ore on the scales 10:39– Unloading high grade green ore at the storage yard 11:15– The Storage Yard 11:53– From the scales the green ore may be taken direct to smelter storage bins 12:16– Ore having as low as 15 to 20 pounds of Copper Nickel to the ton and formerly rejected, is now separated by a system of oil flotation. Low grade ore is first taken to the rock house and broken up 13:01– The flotation mill where low grade ore passes through a series of processes to secure the small amount of valuable metal 13:24– Here the ore is ground as fine as meal between rolls and screened 13:53– The oversize returns to the mill. The fine is mixed with water in a feeder 14:11– The concentrating tables make the first reparation of metal from dross. The concentration or valuable ore pass over and – the dross is watched over the ride. 14:37—The concentration pass to the settling tanks. The rejected ore is carried into a tube mill and ground very fine. 15:02—Very fine ore is carried to first floatation unit, oil, and sulphuric acid are added, and the mixture churned into froth. 15:20—The valuable ore is coated by the oil and floats to the surface into bubbles. 15:36—The remaining ore settles to the bottom and is drown into second unit where it is again churned up and the concentrates removed. 15:54—This process is followed through ten similar units. Finally, the middlings are returned to the head of the system—tailings go to dump. 16:18—Concentrates are sent to settling tank where ore gravitates to bottom—water overflows into receiving trough 16:42— these concentrates also fine green ore from the mines and valuable flue dust from the blast furnaces are fused together in sintering plant. 16:58—Cars of concentrates, fine ore and flue dust are emptied into bins at top of sintering plant. 17:24—Gates measure correct quantities onto endless belt carriers. 17:55—Seperated into two streams – one for each sintering machine 18:16—loading the sintering machine – coarse grain on bottom, fine on top 18:36—an oil blast is forced through the sinter to fire box below causing incipient fusion of all particles together and removing 15% of the sulphur 19:40— The fusion or sponge like formation binds the particles together yet allows free action of furnace blast increasing the furnace capacity for green ore 20:13— The sinter is taken to smelter storage bins 20:18—Loading high grade green ore, sinter, coke and limestone onto furnace charging cars at bottom of storage bins. 21:01—Charging one of the four great furnaces each unit with capacity of 750 tons daily, 4 ½ % metal value. This process is constant. 22:31—Lower section of blast furnaces and water jackets. 22:42: Air pressure pipes—exhausts stack—and passage way from storage bins to smelter. 23:01—22 tons of valuable ore dust is collected in these flue bins daily. 23:20—Flowing at a temperature of 900 to 1050 degrees molten medal is constantly pouring into settler. 23:43—The Settler. The limestone added in furnace charge has heated the iron and rock making it fluid, being lighter this dross rises to the surface in settler and constantly pours off in the form of slag. 24:22—Slag pots, each holding 40 tons being emptied on the slag dump. 25:47—Over 1000 tons of slag are added to this dump every day 26:13—Let us return to the settler. The ore enters the settler—4 ½ % nickel copper from the furnaces. The iron and rock flow off the top as slag. 26:30—The nickel, copper, and some iron gravitate to the bottom and are drawn off at intervals in great ladles. This furnace matte is 16% nickel copper. 27:07—Lifting fifteen tons of molten metal from settler to the magnesite brick lined converters. 27:46—To this molten mass is added silica quartz from Bruce Mine as a flux. 28:02— Adding oxygen under 12lbs, pressure, the iron is Bessemerized at a temperature of 950 to 1100 degrees 28:26—The iron slag is drawn off at intervals and returned to settler where any remaining nickel copper gravitates to bottom 28:50—As ore and quarts are added and slag drawn off, nickel copper deposit gradually rises in convertor to 45 or 50 ton weight when 80% copper nickel called 80% Bessemer Matte is drawn off and poured into moulds. 30:16—Cooling – Breaking – Crushing Matte 31:00 – Measuring –weighing – barreling matte for shipment 32:29—Ore enroute to seaboard 32:45— The smelter equipment. The Power-House, Company’s own Hydro-Electric throughout 33:14—Six Company locomotives are houses here 33:37—General view of Company’s well equipped repair shops 35:12—The store-house where $250,000 worth of stock is kept 35:21—The laboratory is finally equipped for metallurgic work 36:34—The Drafting Room 36:45—The General Offices 37:02—“All aboard for town” 37:27—“Coniston” from the hill-top—1200 population—half mile from smelter 38:14—Bessemer Matte 80% copper-nickel
