Sodium sulfate activation mechanism on co-sulfating

2018-7-1 · Sodium sulfate is a common addition to promote the sulfating process and increase the extraction of value metals, especially in the sulfating of laterite ore whose nickel is substituted in serpentines, hydrous magnesium silicates, goethite or limonite (Jiang et al., 2013, Luo et al., 2009). As more than a third of nickel is hosted in silicate lattices, sodium sulfate was added to accelerate the

Mining Chemicals:SODIUM SULFIDE sodium sulphide

2021-1-10 · Sodium sulfide (Na 2 S) is a de-agent for mixed concentrate of sulfide ore. When the amount of sodium sulfide is large, sodium sulphide can resolve the xanthate collector that adsorbs on the surface of minerals. Therefore, sodium sulfide can be used as a

Mechanism of sodium sulfate in promoting selective

2013-9-10 · A high nickel grade ferronickel was produced from laterite ore using the selective reduction-wet magnetic separation process, with the addition of sodium sulfate (Na 2 SO 4). The ferronickel concentrate assaying 9.87% Ni, with a nickel recovery of 90.90% can be obtained, when laterite ore was reduced at 1200 °C for 50 min with the addition of 10 wt.% Na 2 SO 4 and 2 wt.% coal.

Recovery of Copper by Solution Mining Techniques

2015-7-23 · The mining practice that uses solutions to extract a desired commodity from an ore deposit where it stands without also extracting the rock is known as solution mining. There are essentially two types of solution mining: 1) in-situ and 2) in-place. In-place solution mining requires permeability enhancement techniques such as blasting or
