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, silies, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and nonferrous metals. The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of ...

What is a Rod Mill? (with picture)
An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results. It is, however, limited to maximum rod and drum lengths of approximately 20 feet (6 meters) and is ...
Tailoring ball mill feed size distribution for the ...
This makes feed tailoring in ball milling an interesting parameter to investigate with the aim of maximising the desired mill product. To that end, batch tests were used to investigate the effect of feed tailoring in ball milling using a South African gold ore. Narrowsize feeds of the ore were prepared and milled with 20 and 30 mm sets of singlesize balls using the onesize fraction method ...

gold processing
gold processing gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Goldbearing ore is fed to the milling circuit at about 100 tons/hour. The ore is ground down to product with a particle size of 80% smaller than 75 m ( P 80 = 75 m). A hydrocyclone is used in closed circuit with the mill to separate the product from the outofspeci ion material. The gold is then extracted through a leaching process downstream. The feed to the mill (see Fig. 1) is ...
