How to improve the recovery rate of antimony ore beneficiation? 1. The flotation reagent system is the key to improving the level of mineral processing technology, mainly to find a cost-effective collector for antimony oxide ore, which must be achieved through mineral processing experiments.
The copper-cobalt ore received from Congo contains around 2.0% copper and 0.356% cobalt, with oxidation rates of 92.09% and 88.57% for Cu and Co, respectively. Malachite and cornetite are the main copper minerals, while heterogenite and carrollite are the main Co-bearing minerals. To optimize the leaching efficiency of Cu and Co for this …
Manganese oxide minerals have been used for thousands of years by the ancients for pigments and to clarify glass, and today as ores of manganese metal, catalysts, and battery material.
Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The specific process for selecting copper ore depends mainly on the material …
Extensive research has been carried out on the flotation of copper sulphide ore as compared to copper oxide and mixed type ores. Besides flotation, other beneficiation techniques (selective flocculation and gravity separation) are also discussed in the present review.
production occurs in a variety of ore deposit types; cooper ore has complex ore texture and uneven disseminated particle size; chemical composition of ore is varied. Copper oxide ore occupy for the most of available copper ore resource. And, copper oxide ore is difficult to be concentrated. As a consequence, the research on
