Abstract This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.
اقرأ أكثرOres. Unreactive metals, such as silver and gold, can be found in the Earth's crust in a pure form, uncombined to other elements.However, more reactive metals, such as aluminium and magnesium, will usually be found combined to another element in a compound.An ore is a rock that contains enough of the metal to make it economically worth extracting.
اقرأ أكثرWhen miners find rock containing mineral ore, they first extract the rock from the earth. The rock is then crushed by powerful machinery. Metal is extracted from the crushed ore by one of two major methods: smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore.
