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.
Newmont Mining Corporation pioneered the investigation development and commercialscale implementation of refractory gold wholeore heap biooxidation during a period spanning 19882009 at Carlin Nevada. Basic and applied research and development from 1988 to 1999 included laboratory test work and increasingly larger pilot test heaps culminating in the fullscale
The results are presented in Figure 4 which shows that for the selected consumption bacterial heap leaching can be more economic than BIOX The choice of process obviously depends on individual ore characteristics but for refractory sulphide ores where flotation recovery of gold is below 90 % the bacterial heap leach process should be considered as an alternative to BIOX GOLD
Lowgrade refractory sulphide gold ores exist in which the gold values are too low to economically justify the use of preconcentration processes. The preconcentration process (usually flotation) is followed by the oxidation of the sulphidic concentrate to render the gold amenable to a

The problems that result from refractory gold are caused by Physical encapsulation of disseminated gold particles (usually less than a few micrometers in size) within a mineral that is unreactive and impervious to leaching Chemical interference by one or more of the ore constituents in the cyanide leaching process Physical encapsulation

May be increasing gold recovery from refractory gold ore (with grade 23 g/t) to 9095%?Actual data of top refractory gold ore mines show that gold recovery is 70% and less.
Introduction. Heap leaching is used extensively for the processing of copper and gold ores but there has also been renewed interest in uranium ores as well as recent application to nickel laterites and more frequently the application of heap leaching needs to be considered as part of a larger process in combination with other leaching steps.
