— Analysis of the adsorption capacity of the reagents on the mineral surfaces was based on the total organic carbon (TOC) content remaining in the slurry (Schumacher, 2002). A high TOC content in the slurry indicated a low adsorption capacity of the reagent on the mineral surface because the TOC content added to the flotation cell was constant.

A high pH is important in copper ore processing to maximize this mineral's flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.
