Magnesite (magnesium) Flotation Process. Magnesite (magnesium) is a carbonate mineral. we mainly applied direct flotation process and Reverse Flotation Process for beneficiation of magnesite (magnesium). Reverse flotation process is applied for high grade ore with less calcium & iron (Fe). As for low grade ore, we combines the two methods.
Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
Jul 12, 2017· Dredging Alluvial Gold. The only minerals of any importance which are found in alluvial deposits are gold and other precious metals, tinstone, and those gems which by reason of their hardness and power of resisting chemical changes are preserved in their original state even after being scoured by water for long periods.
alternative process for recovering gold from the tailings generated by the gravimetric process. flotation was selected for further investigation. the feed for the flotation tests was the tailings from a production gravimetric process, in this case a falcon. these tailings are composed of alluvial sand, with particle size varying between less

Gold ore content is very low, in order to extract gold, alluvial gold mining equipment need to broke ore and grind it, and pre-enrichment from the ore to separate gold. It will create favorable conditions for the flotation and cyanidation process, improve the beneficiation index and increase the total recovery of gold.
