Thickening

The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The inlet stream going to a thickener generally is called 'feed' or 'influent'. Overflow from the unit may be called 'overflow', 'effluent', or 'supernatant'.

Copper Mining and Processing: Resources and Glossary

thickening: For copper sulfide ore, a stage in the process of pyrometallurgy, in which the copper froth from the froth floatation stage is poured into large tanks called thickeners, where the copper solids settle and are filtered to remove excess water; this copper concentrate will then undergo smelting.
