Frothing in chemistry
WebSep 26, 2024 · The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper. Web16.1.2 Frothers. Frothers are surfactants, usually organic heteropolar compounds such as alcohols or polyglycol ethers. Due to the heteropolar nature, the frother adsorbs at the air/water interface and as a result, lowers the water surface tension. This has the effect of producing smaller bubbles and more importantly it stabilises the froth ...
