    • Froth flotation

      Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

      In this study, ethylene diamine phosphate (EDP) was employed as an activator to improve the sulfidization and flotation of chrysocolla. The micro flotation experiment results indicated that EDP could greatly increase the flotation recovery of chrysocolla. BET and TEM measurements confirmed that the porous structure of the chrysocollas surface would lead to large amounts of the reagents.
