Ball mill

Ball mill

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.

principle of froth floatation  Chemistry  General

principle of froth floatation Chemistry General

Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral. The ore is ground into a fine powder and

Dry Grinding VS Wet Grinding Mineral Processing amp; Metallurgy

The choice between wet and dry milling is, in general, unimportant in smallscale milling but is a major technical problem when largescale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the

Lime use and functionality in sulphide mineral flotation

Primary grinding Lime is often added into the semiautogenous (SAG) mill together with the ore feed and process water. Sulfide minerals are, by nature, acid to varying degrees causing the milled pulp to have a pH ranging from 4 to 8 depending on the sulphide and gangue mineral composition of the ore.
