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.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors.. As in all mining operations the ore must usually be beneficiated (concentrated).
This page looks at the extraction of copper from its ores its purification by electrolysis and some of its uses. Before you get too bogged down in the extraction of copper make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of
A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.
The kinetic curves for gold copper and cyanide for the pyrite concentrate are shown in Fig. 2 at an initial cyanide concentration of 300 ppm. Fig. 2 indicates that the copper leaches rapidly into solution consuming all the free cyanide available. This copper then partially precipitates as it forms a weaker cyanide complex than gold and the
The case study shows that when targeting a nominal metal recovery of 90 per cent for gold the HVP preconcentration technique can split the low grade ore (0.9 ppm gold and 0.28 per cent copper in the feed size 26.537.5 mm) into two components a low grade oversize material (0.3 ppm gold and 0.15 per cent copper) and a high grade undersize material (1.0 ppm gold and 0.3 per cent copper).

The four major steps in the production of marketable copper are mining concentrating smelting and refining. In a few instances however leaching takes the place of concentrating smelting and refining. At present although considerable leaching and directsmelting ores are produced the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
The concentration of a mineral in the ore body (i.e. % or g/t) 2% copper and 1.5 gram per tonne gold. Strike Length. The length in which the mineralization is found in the ore body. (horizontally) 500 meters. Depth. The depth in which the mineralization is found in the ore body (vertically) 200 meters.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore to 4 000 million tonnes or more and have a grade of between 0.2% and 5% copper with gold
