1. 2.4 thiosulfate leaching of
concentrate casapalca (Peru), Banska hodrusa (Slovakia) and atacocha (Peru) was studied under the conditions provided in Table 3
3. Results and discussion
3.1 mechanochemical pretreatment and mechanical activation
mechanochemical pretreatment of concentrate casapalca in alkaline solution (Na2S + NaOH) includes grinding and leaching, They have a combined effect. Grinding destroys the silver bearing tetrahedrite, and grinding destroys the silver bearing tetrahedrite, which decomposes e to simultaneous leaching, and there is no antimony in the leaching. The content of sb has decreased from 8.3% to 1.02%, indicating the destruction of tetrahedrite. This is consistent with the previous paper on the mechanochemical alkaline leaching of tetrahedrite (balaz et al., 1994; Balaz and kammel, 1996)
a typical change in all concentrates in the mill e to mechanochemical pretreatment and / or mechanical activation is an increase in specific surface area SA (Table 4). This change has an effect on the extraction rate and recovery rate of silver, gold and bismuth from the concentrate used
3.2 effect of mechanochemical pretreatment and mechanical activation on thiosulfate leaching of silver, gold and bismuth
mechanochemical pretreatment and mechanical activation proved to be an effective method for reprocessing complex sulfide concentrate before extracting silver, gold and bismuth into leaching solution.
