Use of humic substances in froth flotation processes ...

Film flotation tests showed that biosolids and HAs can be used as environmental-friendly collectors in froth flotation processes since they modify the copper sulfide ore hydrophobicity. The ability to form and stabilize foams of biosolids and HAs are evaluated by the Bikerman test Reyes-Bozo et al., 2011a , Reyes-Bozo et al., 2011b .

DAF FPAC - Dissolved Air Flotation System - DAF |

2 The DAF FPAC flotation system is a large surface air flotation system with cross flow separation. The system has been designed to treat wastewater flows heavily loaded with solids that need significant amounts of free surface area for successful flotation and separation up to 40kg of solids per m of free surface area inside the system can be treated.

US Patent for Frothless flotation apparatus Patent

A novel apparatus for use in frothless flotation. The apparatus includes a cover which is sealingly engaged to the top of the flotation column and a wash-water tank in communication with the upper part of the flotation column wherein the level in the wash-water tank is maintained at or above the level of the cover thereby preventing the formation of a froth layer in the column.

1 Froth Flotation Fundamental Principles

2009-8-271 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineralwater slurry. The particles with attached air bubbles are then carried to the surface and
