gypsum flotation is very similar to calcium carbonate flotation but depends as well on the morphology of the material, whether it is scale like or crystal like. The general flotation of gypsum is with fatty acid type collectors with a weak frother added to help the froth be a little more stable.

(easily oxidized to gypsum) and calcium sulfate (gypsum), as raw materials for the wallboard or plaster industries. Froth flotation was selected as the purifiion method because it works well for the separation of small particles and is a proven technology that
How to Extract Precious Metals From Sulfides Sciencing
How to Extract Precious Metals From Sulfides The most popular method of separation is the froth floatation method, which was specifically designed for sulfides as opposed to smelting which is more suitable for larger veins of metal ore. Another more modern method uses microorganisms to separate the metals from the sulfur.

This paper aims to understand the fundamental interaction mechanism between molybdenite and kaolinite in gypsum solution using kerosene as collector. Microflotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral. The results showed that the recovery of molybdenite decreased from 86% to 74%

The flotation tests were conducted for the precipitates thus formed. It was touiid that zinc hydroxide was effectively separated from gypsum with SDS collector when sodium silie was aaaea in Dotn procelss of neutralization and flotation, and that some 90% of gypsum was recovered in the froth and 87% of zinc hydroxide in te tailing solution.

This study showed that FGD gypsum could be considered as an attractive material for silie removal from scheelite flotation wastewater. FGD gypsum can release sufficient calcium ions for the formation of calcium silie. Initial pH is a key factor on silie removal by influencing calcium release and precipitation reaction.

A leachate is any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed.. Leachate is a widely used term in the environmental sciences where it has the specific meaning of a liquid that has dissolved or entrained environmentally harmful substances that may then enter the environment.
