Application of Thionocarbamates in Copper Slag Flotation

Thionocarbamates are the group of collectors that mostly used for flotation sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition ore. In this paper, results study application thionocarbamates slag presented. Chemical analysis smelter sample obtained from Flotation plant Bor, Serbia, showed it contains 3.56% copper, which over 73% is form, as well 0.58 g/t gold and 11.30 silver. XRD identified fayalite magnetite main minerals present SEM-EDS mainly form thus making suitable thionocarbamates. Two MX 980 TC 1000 one xanthate SIPX, along their mixtures + SIPX were investigated. The influence parameters such collector type dosage, grinding fineness, pulps’ pH time, indicators (recovery, yield grade concentrate) determined. Smaller dosages (40 g/t) provided concentrates high grades, 22.34% (MX 980) 18.42% (TC 1000) lower recovery rates, 83.98% 87.78% 1000), while increase to 200 led rates more than 4% significant decrease grades. fineness 50% 70% grain size < 0.074 mm positive impact indicators, rate, yield, all investigated mixtures, while, further 90%, continued grades decreased. had influence, especially 980, increased 8 10 (12). A kinetics test was fastest, i.e., rate after 20 min 91%, recoveries other few percentage points lower.
