Leaching of Silver from Boorchi Ag-Pb Ore in Mongolia with Acidic Thiourea Solution
A hydrometallurgical process to extract silver from the silver-lead ore in Boorchi,Mongolia by using thiourea leaching solution is studied in this work.Through the observation of optical and scanning electron microscopes,and energy spectral analysis,it ...

Leaching of a silver bearing sulphide by-product with cyanide, thiourea and chloride solutions
The aim of this research was to increase the value of sulphide tailings assaying 1000-1500 g/ton Ag per tonne and high arsenic (about 13%) content. The sulphides were characterized and it was verified that silver occurs both as mathildite, AgBiS2, and in

Noncyanide leaching of an auriferous pyrite ore from Ecuador [PDF]
journal articleGold leaching of an auriferous pyrite ore from the Portovelo deposit in Ecuador indicates that noncyanide leaching systems, such as thiocyanate and thiourea, are not as effective as the traditional cyanide system.

Transformation of Herbicide Propachlor by an Agrochemical Thiourea
Propachlor and other chloroacetanilide herbicides are frequently detected contaminants of groundwater and surface water in agricultural regions. The purpose of this work was to develop a new approach to remove propachlor residues from the environment via

The prospects for an alternative gold leach reagent: Thiourea
Gold has been traditionally extracted from ores by leaching with an alkaline cyanide solution. However, certain characteristics and drawbacks of cyanidation process have stimulated research into alternative processes.
