·Pressure oxidation is a widely accepted method to treat refractory gold ores Gold recovery is generally lower from alkaline than acidic pressure oxidation discharge due to passivation and incomplete oxidation of mineral Gold ore from Goldstrike NV is a typical refractory gold ore containing sulfide and carbonaceous matter Alkaline pressure oxidation
·01 What are the types of gold ore Gold ore exists in various forms and compositions each with its own characteristics The following are common types of gold ore 1 Free gold Gold particles can be observed in the ore and are easily separated from the surrounding gangue are generally easier to process and extract gold from than
·The technological processing flowsheet for gold bearing ores varies widely The choice of a particular technological flowsheet depends on several factors including the nature of the gold in the ore especially its size and chemical composition the nature of the minerals associated with the gold the presence of other valuable components in the ore and the
·Oxide copper gold ores The presence of clay minerals prevents flotation of these ores Ester modified xanthates have been used with some success to treat gold containing oxide copper ores using a sulphidization method Chlorine/chloride based methods require special stainless steel and rubber lined equipment to deal with corrosive and
·The greatest promise for the bromine leach process was with oxidized gold ores The recovery of gold from oxide ores with bromine was comparable to that achievable with cyanide and bromine
·Ores may also be treated with H 2 SO 4 at 250 °C to convert the lithium present in the ores into Li 2 SO 4 from which lithium can be recovered using a pregnant leach solution Tran and Luong 2015 Liu et al 2019 studied the leaching kinetics of lithium from lepidolite by using an H 2 SO 4 solution The results show that % lithium
·Adding tellurium to other metals improves their strength and hardness and reduces corrosion It can also be used for tinting glass and is vital to the manufacture of solar panels Where does tellurium come from Tellurium is found in copper ore and most often extracted as a by product of copper processing Tellurium is mined in Japan and Canada 3
