is it possible to recover chrome ores from slimes at zimasco

Physical Processing: Innovations in Mineral Processing

The continuous HGMS made it possible to process ores with a high content (+10 %) of weakly magnetic material. The magnetic intensity for typical magnetite ore applications vary from around 800 to 1800 G, whereas for removing weakly magnetic components from kaolin clays requires a minimum of 18,000–20,000 G.

Recovery of metal from slag/mixed metal generated in

2005/1/6It was possible to recover only 1.1% of metal with 59% chromium (Sripriya et al., 1996). Subsequently, large-scale magnetic separation and jigging tests were also carried out. The magnetic separation was carried out in a dry belt magnetic separator in which the magnetic roll assembly consisted of a motor driven magnetic roll, an idler roll (which freely rotates), and a moving belt.

US Patent for Process for recovering gold and silver from

These ores are called refractory ores. Poor gold recovery from refractory ores is typically caused by the gold being occluded in sulfide mineral grains (usually pyrite and arsenopyrite grains) so that the gold cannot react with the cyanide leach solution or by cyanide-dissolved gold being adsorbed by carbonaceous material present in the ore (this phenomenon is known as "preg robbing").

process for recovering chrome from tailings

New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. Get price

「flotation of low grade iron ore」

Sep 19, 2017 Due to gradual depletion of highgrade iron ores, there is a need to investigate the treatment of lowgrade iron ores. Current procedures are time and cost intensive.
