Application Of Sart To Heap Leaching Of Gold
For every kg of cyanide soluble copper extracted. therefore, if the ore has 40 g/t of cyanide-soluble copper, then the minimum quantity of cyanide required for copper leaching is 0.1 kg nacn/t. if the quantity of copper extracted increases to 300 g/t then the cyanide requirement increases to 0.7 kg nacn/t. viewed another way, since the 3.
Benefits Of Agglomeration In An Sx
High-grade copper ores are becoming a thing of the past, with most ore falling in the range of . 5% – 2%. even deposits now considered to be high grade must still first be concentrated for smelting. this will likely further increase the importance of the sx-ew process in future copper.
