With a telluride-type gold ore flotation concentrate as the research object, the Na 2 S + NaOH collaborative leaching process was applied to selectively separate tellurium before the cyanide leaching of gold and silver. The effects of process parameters including the type of leaching agent, the amount of leaching agent, liquid-solid ratio, …

Synopsis. Alkaline sulphide leaching was adopted to extract tellurium from tellurium-bearing gold concentrate for the first time. The tellurium leaching kinetics were studied. The influence of average particle size, stirring speed, leaching temperature, Na2S concentration, and NaOH concentration on the tellurium extraction were investigated.

When heated in air to around 500°C the gold tellurium bond is readily broken, producing tellurium dioxide and gold metal. Above 800°C the TeO 2 sublimes off. The mineral itself is remarkably gold rich with the gold being found in a molecular association with the element tellurium. On a weight basis some 44% of the weight of the …

08 March 2021. share. SALT LAKE CITY--(BUSINESS WIRE)--Rio Tinto will begin construction on a new plant that will recover tellurium, a critical mineral used in solar panels, from copper refining at its Kennecott mine near Salt Lake City, Utah. Rio Tinto is investing $2.9 million to set up the plant, which will recover tellurium as a byproduct ...

Gold is sometimes found in association with sphalerite [(Zn,Fe)S], although the association is rather rare. When the mineralogy is favourable and the concentration of gold warrants it, the possibility of separating gold from the zinc at the concentrator is real. One such example is given by Minera El Toqui in Chile (Anon, 1993).

The selection and dosage of collectors and pulp pH are very important to produce one concentrate containing tellurides and free gold, and a further …

Then, NaClO 3-H 2 SO 4-NaCl solution was adopted to selectively leach gold from oxidative acid leaching residue, and the leached gold was recovered by H 2 C 2 O 4 reduction. Finally, Na 2 SO 3 leaching with a sealed reactor was utilized to efficiently extract silver from chloride leaching residue, and Na 2 S 2 O 4 was employed to recover the ...

The kinetic analysis showed that the leaching process of tellurium from telluride-type gold concentrate was a mixed type of chemical reaction control and diffusion control. The grain parameter in the leaching process was 0.26263 and the apparent activation energy E = 17.12 kJ/mol. Tellurium could be pre-leached from the telluride-type gold ...
