2018-06-15· Indium is produced in small amounts from the mining of Zn ores, and the sheer number of smart phones, tablets etc. produced each year requires around 700 tonnes per year of indium. Recent estimates however, suggest that total reserves are around 16,000 tonnes, so it is a very finite resource, and great efforts are being made to recycle it.

Kinetics of flotation - CONCENTRATION OF MINERALS

Flotation kinetics (from the Greek Kinētikós - driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R = f ( t ).

THE RECOVERY OF INDIUM FROM MINING WASTES

sample which is a waste from flotation plant, a "jarosite" sample which is a waste from a hydrometallurgical plant, and a "ferrite" sample which is a waste from pyro-hydrometallurgical plant. Characterization work conducted showed that the tailings sample was mainly comprised of silicates minerals such as quartz, muscovite, and feldspar, that the jarosite sample was mainly comprised of ...

InZinc Mining Ltd. - Preliminary Economic Assessment

Metallurgical test work confirmed that the underground resources of the West Desert project are amenable to conventional flotation processing to produce marketable zinc and copper concentrates. The concentrates will contain significant levels of indium and precious metals. Test work also demonstrated that a marketable iron (magnetite) concentrate can be produced at very high recoveries and low ...
