Gravity Separation Of Copper Slag

Rapid Separation of Copper Phase and Iron-Rich Phase From

Fe3O4 particles dispersed among the copper slag were transformed into FeO by adding an appropriate amount of carbon as a reducing agent, forming the slag melt with SiO2 at low temperature and assisting separation of the copper phase from the slag. Consequently, in a super-gravity field, the metallic copper and copper matte were concentrated as

The density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3, which means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.

Copper extraction

When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separationcircuit where the density of the metal is used to liberate it from the lighter silicate minerals. Often, the nature of the gangue is important, as clay-rich native copper ores prove difficult to liberate.

The Benefits of Using Gravity E & MJ

The leading suppliers offer their outlook on the current state of gravity-separation technology. By Simon Walker, European Editor. With the possible exception of visual sorting—”this one’s green, this one’s not,” or however the Bronze Age equivalent ran—being able to separate minerals using differences in their density is the most ancient mineral-processing technique known to man.
