Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Electrorefining is another common method used in refining applications but first requires than an impure silver anode is cast from the feed material. Electrorefining is very similar to electrowinning the difference being that in electrorefining the anode
Silver electrorefining is straightforward involving the anodic dissolution of silver and base metals from the anode and the simultaneous cathodic reduction of silver at the cathode (Reactions (34.20) and (34.21) respectively) (34.20) Anodic dissolution Ag o
Ok so let's say I have raw silver which is polluted with a bit of gold copper and lead. So through electrorefining I want to make pure silver out of it. Let's say I have it all in an acidic solu...
With Outotec HCD (High Current Density) silver electrorefining cells current densities exceeding 1000 A/m2 are possible depending on the composition of the silver Doré anodes being processed. The electrorefining process is continuous except when new silver Doré anodes are loaded in the cells and silver anode slime and anode scrap is discharged from the cells at the end of the electrolysis cycle.
high grade silver with an impurity content less than 0.01 wt.%. These grades are needed especially for industrial use purposes. Furthermore the silver electrolysis enables to separate the contained precious metals such as Au or PGMs. In the electrorefining the crude silver anodes are dissolved in a nitric acid silver nitrate solution and the

The residue from silver refining is treated by affination or parting to concentrate the gold content which is refined by the Wohlwill process. From zinc concentrates Zinc concentrates are roasted and then leached with sulfuric acid to dissolve their zinc content leaving a residue that contains lead silver and goldalong with 5 to 10 percent of the zinc content of the concentrates.
