Gold Leaching from an Oxide Ore Using Thiocyanate as a …

Abstract. Thiocyanate (SCN –) is a promising alternative to cyanide as a lixiviant for gold extraction and is 1000 times less toxic than cyanide.In this study, the following leaching parameters were tested to optimize the gold recovery for the first time from an oxide ore using the response surface methodology: initial thiocyanate concentration (10–500 mM), initial Fe 3+ …

Silver Chlorination Leaching by Trough Method

In tank-lixiviation of silver by chlorination, the extraction of the silver from chloridized ore by solutions of hyposulphite salts is performed by filtration.The ore-particles are kept stationary, while the solvent moves down through the mass of ore. The quickness of extraction, other conditions alike, is in direct proportion to the rapidity of the movement of the …

Gold leaching from ores using biogenic lixiviants – A review

The chemical analysis of the ore sample indicated that the ore contained mainly iron (3.5%), copper (0.5%), and aluminum (0.5%) (Table 1). To dissolve those cyanide-consuming metals, pretreatment of the ore ( Table 1 ) for 24 h was applied using 6 M nitric acid at 25 °C and 25% w/w solid content.

Full article: World mineral loss and possibility to increase ore

This corresponds to a vast amount of mineral loss for the world every year. Taking iron ore as example, the total loss of this ore in the year 2018 would be 1087 Mt, corresponding to the actual production 2923 Mt in the same year. This ore loss is equivalent to the production of 1087 iron ore mines each of which has an annual production of 1 Mt.

Maximize Precious Metals Recovery with CCD Circuits and …

Clearly the assessment is simplistic (perhaps absurdly so). But it illustrates the point: As the cost of groundwork increases, high-density and/or paste thickeners become more cost competitive. At the higher end of our example, the earthwork more than offsets the added cost of the thickener ($1,850,000 versus $1,800,000).
