Recovery of copper from dump slag by a segregation process

A thermogravimetric study of copper chlorination

“…The chlorination reactions of copper or copper-containing mixtures were studied for the development of separation methods in extractive metallurgy [1][2][3][4][5], for the recycling of metals from scraps [6,7] or from spent catalysts [8,9], and for preparation of anhydrous chlorides as precursors for further chemical industrial applications [10,11].…”

Effect of annealing treatment on the crystallisation and leaching of dumped base metal smelter slags

“…Various techniques including oxidative or reductive leaching, carbothermal reduction with or without slag modifiers were investigated by several metal producing units worldwide for metals beneficiation or for the chemical stabilisation of toxic heavy metals such as Cr, Pb, etc. contained in the smelter wastes [1,[5][6][7][8][9][10][11][12][13]. Leaching test of steel slags showed that the solubility of elements such as Cr, Mo and V from slag modified by means of re-melting and water-granulation, as well as by re-melting and semi-rapid cooling in crucibles was very low [14][15][16].…”

Crystal formation and growth by slow cooling for recovery of magnetite particles from copper smelting slag

“…Flotation (Bruckard et al, 2004;Roy et al, 2015), and leaching (Banza et al, 2002;Kaksonen et al, 2017Kaksonen et al, , 2011Muravyov et al, 2012;Nadirov et al, 2013) are typical methods used to recover metals from copper smelting slag. In addition, roasting is widely performed as a preprocessing step before flotation and/or leaching because some metals are converted into form that can be separated from the slag (Rudnik et al, 2009;Vircikova and Molnar, 1992). Following the roasting process, rapid and slow cooling methods may be applied.…”
