احصل على السعرThis work investigates the effect of an agglomeration and curing pretreatment on leaching of a copper sulfide ore, mainly chalcopyrite, using mini columns in acid nitrate chloride media. Ten pretreatment tests were conducted to evaluate different variables, namely the addition of nitrate as NaNO3 ( and kg/ton), chloride as NaCl ( and kg/ton), curing time (20 and 30 days) and
احصل على السعرAccidental activation of sphalerite by Cu 2+ ions released from copper minerals can be countered by the addition of cyanide. In this role the cyanide could be classed as a deactivator . The cyanide acts by reacting with copper in solution, first reducing Cu 2+ to Cu + then forming soluble cupro cyanide complexes, Cu(CN) x 1− x (, Cu(CN) 2 − ), which are stable and prevent the uptake of

احصل على السعرCopper piping has a very smooth surface which gives the hardness minerals in the water no place to catch onto, therefore there is no starting point for a build up of hardness to take place. I have found that homes with copper piping and hard water will have minimal build up within the pipes, even after decades of hard water flowing through them.
