Of sphalerite contained within the copper concentrate, about 93% occurs as free grains, Beneficiation of a tin-sulphide ore 25 representing 38 % of total sample weight. 92 % of locked material occurs as unliberated sphalerite - chalcopyrite. Poor liberation between chalcopyrite and sphalerite therefore does not appear to be the reason for ...

a complete roasting of the ore is nearly impossible when working under reconstructed prehistoric conditions, es-pecially if the ore pieces are several millimetres to centi-metres in size: as the size of the pieces increases, the dif-fusion of oxygen into the interior of the ore is impeded, leading to a stagnation of the oxidation process (Burger,
