Ammoniacal Percolation Leaching of Copper Ores Canadian ,

Jul 18, 2013 0183 32 AbstractThe general feasibility of ammoniacal percolation leaching of copper sulphide ores has been demonstrated The rates are comparable to those of conventional ferric sulphate-sulphuric acid systems, but without the attendant problems of carbonate or iron dissolution, For the ore column heights studied, the copper leaching rate increased approximately as the square root of the total NH3 ....

Benefits of Agglomeration in an SX

Heap Leaching Copper Ore with Agglomeration Crushed copper ore is first typically processed via heap leaching An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator...

Percolation Leaching of Bornite Ore

Up to 80 per cent of the copper in a bornite ore can be quickly leached with percolating acidified ferric sulphate solutions The upper limit for rapid copper extraction is set by the conversion of bornite to slowly dissolving chalcopyrite The dissolution occurs in two stages a rapid linear initial stage, followed by a ,...

Percolation leaching method

It is generally known in metallurgical leaching practice that there is a minimum degree of fineness to which ore particles may be crushed for subsequent percolation leaching The reason for this is because the leaching column becomes clogged by the fine material, thus preventing the desired rate of solution percolation...
