They are apt to be high in sulphur from the presence of pyrite and copper pyrites. Garnet epidote pyroxene and apatite are found in the wall rock as well as in the ore. The magnetite deposits of the islands along the Pacific coast British Columbia are of this type as are also many of those of southeastern Ontario and the adjoining part get price
They do their treatment in a pressurized container called an autoclave which greatly speeds up the oxygen treatment process. For small scale treatment by individuals t he method is to grind the ore up finely put it in some sort of tub and keep it moist. Stir and turn it over from time to time to allow the air access to the material.get price

extracting and concentrating the metallic ore. In almost every case metallic ores are buried under a layer of ordinary soil or rock (called overburden or waste rock ) that must be moved or excavated to allow access to the ore deposit. The first way in which proposed mining projects differ is the proposed method of moving orget price
Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold silver and copper are common metals that are found within ore and stamp mills allow these metals to be released from rock for further processing and refining.get price
Ironmaking the first step in making steel involves the raw inputs of iron ore coke and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5 carbon and other impurities that make it brittle.get price
The inside of the mill is lined with lifting plates to lift the material inside the mill where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold copper and platinum mines with applications also in the lead zinc silver alumina and nickel industries.get price
The production of the metal Aluminum from the raw ore of Bauxite is a two stage process. Stage 1. The grinding mill rotates like a huge drum while steel rods rolling around loose inside the mill grind the ore to an even finer consistency. Alumina crystals begin to grow around the seeds then settle to the bottom of the tank where they get price
Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99.99 pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different get price

Palladium is normally a platinum group Metal (PGM). It is a rare element and occurs along with deposits of platinum nickel copper silver and gold and is therefore obtained as a byproduct of mining these metals i.e. PGM. The mining of palladium is a very intricate process because of the fact that palladium is so spread out under the surface and in the mines and requires using mechanical get price
heat is used to raise the temperature of an ore because most chemical reactions happen faster at high temperatures this process helps change the chemical state of the iron metal atoms which forces them to break their bonds with non-iron atoms.get price
Iron ore and other iron bearing materials coke and limestone are charged into the furnace from the top and work their way down becoming hotter as they sink in the body of the furnace which is called the stack. In the top half of the furnace gas from burning coke removes a great deal of oxygen from the iron ore.get price
Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 copper.get price
Iron ore is smelted in a blast furnace Superheated air—up to 2 200°F—is "blasted" into the furnace causing it to burn much hotter than it otherwise could. A typical blast furnace at a steel mill runs for 24 hours a day 365 days a weeks for up to 20 years before it must be replaced. Pure steel is very susceptible to rust.get price
Mineral processing art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.get price
Aug 17 2015 · The concept of net energy must be applied to renewable sources of energy such as windmills and photovoltaics. A two-megawatt windmill contains 260 tonnes of steel requiring 170 tonnes of cokingget price
The rock is drilled and blasted then moved to the surface by truck belt conveyor or elevator. Once at the surface the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods which generally cost less than underground methods.get price
The coke reduces the iron oxide in the ore to metallic iron and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled and marketed as pig iron the rest flows into basic oxygen furnaces where it is converted into steel.get price

Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.get price
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.get price

The samples can be taken from adits pits trenches etc. in the ore body or they can be crushed drill cores.While it is helpful in anticipating variations in feed rates to know the grindability of the various ore types in a deposit for mill selection grindability tests should be run on composite samples representative of the blended mill feed.get price

the ore is reduced to 3/4" or less it moves out of the mill in a slurry solution. The mill discharge is screened at 1/4" on trommel screens attached to the mill. Ore smaller than 1/4" is pumped in slurry solution to the wet cobber magnetic separator which begins the process of separating the iron from the non-iron material. The magnetic iron get price
