First, the actual and program When using the stage mining method and the mining method, the ratio of the reserves of the ore column varies greatly with the thickness of the ore body. The reserves of thin and extremely thin and steeply inclined veins are generally not more than 5.10%, and can reach.....
The processing of detonating detonators and kits must be carried out in a specialized processing room or in a safer place. No idlers are allowed to operate. When processing the detonator, first cut the fuse according to the required length, slowly insert the end of the hand into the fire tube, and.....
I. Overview China's factories use P204 organic solvent extraction method to extract indium from smelting intermediates. The advantages are: (1) P204 has good selectivity to indium and can extract indium from a mixture containing very low indium. (2) The extraction enrichment rate is up to 10.....
(2) Periodic curve with stationary period The periodic curve with stationary period is shown in Fig. 2, also known as Meyer curve. The entire bed can be lifted in a rapid increase in flow, then the flow is stationary relative to the water velocity decreases, loose long period, large amount of pro.....
In the ore beneficiation process of Baiyun Obo, the process of reduction roasting-magnetic separation (recovery of iron )-flotation (recovering rare earth, fluorite and other minerals) plays an important role. It is of practical significance to study the effect of reduction roasting on the floatabi.....
Gold ores containing antimony have often associated arsenopyrite and pyrite, this mineral is a complex of antimony important types. It has greater economic value than a single antimony ore. Gold exists in the microscopic and submicroscopic natural gold in the ore. It is embedded in stibnite, arseno.....
I. Introduction With the exploitation of mineral resources of gold, easy to deal with dwindling ore; currently 60% of the refractory gold ores of gold reserves Jin Zhanshi sector. The so-called "difficult to handle" means that the gold in the ore cannot be effectively extracted by conven.....
