Location of Florida gold silver Mine south of Santiago central Chile Chemical real time monitoring was performed in the thickener and in a control well red marks located in the mining area
Guo et al [5] recovered gold and silver elements with high recovery efficiencies of % and % from a refractory gold tailing by an iodination roasting technology They concluded that this new technology was a promising route to recover different kinds of gold and silver residues from metal tailings
Gold tailing is residue waste but it s also a secondary resource Thus far little is known about the iodination roasting and it was first used to dispose gold tailing Here we show that iodination roasting can efficient recovery of gold and silver from the
The process was applied to a mining tailing containing both metallic and silver sulfides having a similar behavior to that observed by previous authors using silver powder and silver plate Graphical abstract Download Download full size image; Ag and Au is shown in Table 2 The size distribution results demonstrate that the mineral
