The process sequence is shown in figure 7. The Ag2S precipitation-carbon adsorption processing method is being evaluated at a heap-leach cyanidation installation by Sand Springs Co., Fallon, Nev., for processing a silver ore low in gold content. silver-free filtrate can then be electrolyzed to win the gold by deposition on steel wool cathodes.

Actually, researches on cement kilns co-processing MSWI fly ash have been done as the MSWI fly ash riches in calcium that the process of cement production needs (Liu et al., 2015, 2016; ... For iron ore sintering process, both the calcium and iron are necessities. Therefore, the similarities of chemical compositions made iron ore sintering ...

Solid recovered fuel (SRF according to EN 15359) is frequently used to substitute primary fuels required for the clinker burning process in the cement industry. Since the ash that is formed during the combustion of the SRF is directly incorporated into the product portland cement clinker, this process is also referred to as "co-processing".
