What is Flotation Process in Mining Industry?
The mixed flotation process is a commonly used process in the flotation of polymetallic sulfide ores. First, all the useful minerals are mixed and floated, and then the useful minerals in the mixed concentrate are separated one by one. This process is suitable for useful minerals grade comparison. Low (more gangue content) and useful minerals ...

Gold Milling Process -Primitive and Basic
As about 40 per cent, of the ore will pass through a 6,400 sieve, there must be much over-stamping, resulting, no doubt, in the production of a great deal of float-gold and slimes. After the mill has been running for a longer or shorter period, according to circumstances, a clean-up takes place. The crushed ore is carried out in large wooden ...

The Mill recovered metals from the ore by gravity separation and by selective flotation. Sulfide ore minerals were concentrated by froth flotation, a method used in the early twentieth century that allowed processing of ores. The original mill equipment is still in working order. It is the only intact and functional mill of its kind in Colorado.
