Rod mills, how they function
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...

Smelting and Roasting Ores to recover gold, silver and ...
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Tungsten: extraction and processingMetalpedia
Tungsten scrap is a very valuable raw material due to its high tungsten content in comparison to ore. Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores. If present, cobalt, tantalum and niobium are recovered in separate processing lines. Other tungsten ...
Tungsten
The ore is eventually converted to tungsten(VI) oxide (WO 3), which is heated with hydrogen or carbon to produce powdered tungsten. Because of tungsten's high melting point, it is not commercially feasible to cast tungsten ingots. Instead, powdered tungsten is mixed with small amounts of powdered nickel or other metals, and sintered. During the sintering process, the nickel diffuses into the ...

Tungsten is a rare acidforming heavy metal found chiefly in the tungstates of iron and calcium, wolframite and scheelite. Tungsten is not found native, but is produced in the form of a greyishblack powder, which when fused has a specific gravity of, virtually the same as gold at I recent years some cases of gold plated tungsten bars masquerading as gold have surfaced.

Grinding
The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 510 cm in diameter but gradually wear out.
Tungsten Concentrates
Producing Tungsten Concentrates. Cone crushers and ball mills reduce the size of the ore to under 2mm in size. Water carries the ore over shaker tables to concentrate it. It works like panning for gold in a river. The ore particles with lower density flow off as tailings while the higher density tungsten concentrate remains.
