For sulfide ores, both secondary and primary, froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper, this mineral can be recovered by a simple gravity circuit. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.The following steps depend on the nature of the ore containing the copper.
It is essential to optimize the granite quarry plant design and layout, and launched a most effective quarrying solution for higher production and capacity. You will find a number of factors should consider so as developing a cost-effective granite quarry plant.

Mice were observed separately for 30 min, daily for 24 h, with rigorous observation in the first 4 h, and daily for 14 days. The individual weights of each mouse were determined before the administration of the test product and were re-calculated at the end of the 14 days. The toxicological evaluation was performed in 4 groups (n = 20). Each animal received a single dose of tocosh flour suspension at 10 mL/kg body weight. Group I (n = 5 males) and Group II (n = 5 females) received a single dose of 2000 mg/Kg body weight respectively, Group III (n = 5 males) and IV (n = 5 females): mice received a dose of 5000 mg/Kg BW, respectively. Next, the animals were weighed and the test substance was administered.Mice were kept with water ad libitum and were fasted for a fixed period such as 4–6 h before the administration of samples.
