Froth Flotation Method - JXSC Machine
The flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some gold-bearing pyrite and pyrrhotite, it is suitable for flotation in weak acid pulp medium. Oxygen has an effect on the flotation process of gold-silver sulfide ore oxidized to different degrees.

Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Ball mill - Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
