ore concentraion processes

Extractive metallurgy - Wikipedia

When an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter ...

ore crushing and concentrating processes - amastuola.eu

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper.

Mineral processing - Wikipedia

The range of process options is limited by the nature of the ore. Being oxides, laterites are not amenable to conventional concentration processes, so that large tonnages must be smelted. In addition, they contain large amounts of water (in the range of 35 to 40 percent) as moisture and chemically bound in the form of hydroxides.

Iron ore concentration - npo-center.com

The process used is froth flotation, a succession of stages each delivering a greater concentration of the lead ore. The ore, containing gangue (which typically contains 3-8% lead) is ground with water to a particle size similar to that of fine sand (<0.25 mm).
