Optimization of physicochemical parameters of pyrite flotation

Sep 23, 2016 Tailings issued from polymetallic ore flotation of Chaabat el-Hamra mine contain sulfides such as Galena (PbS), Pyrite (FeS2) and Chalcopyrite (CuFeS2). They present environmental threats such as the acid mine drainage. Chemical analysis showed that the major element of these tailings is Pyrite. The processing of the latter eliminates much of the sulfur.

Physico-chemical Water Treatment Processes IWA Publishing

Physico-chemical treatment of wastewater focuses primarily on the separation of colloidal particles. This is achieved through the addition of chemicals (called coagulants and flocculants). These change the physical state of the colloids allowing them to remain in an indefinitely stable form and therefore form into particles or flocs with settling properties (3, 4 and 5).
