subject: The Characteristics And Progress Of Manganese Ore [print this page] The characteristics and progress of manganese ore
The types of manganese ore are various, but the basic beneficiation method is similar to that of weakly magnetic iron ore beneficiation, the unique points are below:
(1) There are many methods of mineral processing equipment, and can be multi-jointed, and almost every job in the joint process can produce qualified concentrates.
A washing: manganese beneficiation processes basically involve screening washing job. As to some rich oxide ores, you can get a taste of the high end concentrates from the job. There are some ore by washing get into the next job beneficiation, not only can improve the taste of the inclusion ore, more importantly, can significantly improve the job anterograde.
B beneficiation process is fractionated for re-election, magnetic, flotation, each can get various fractions commodity concentrate.
C In addition to the special minerals or relatively fine-grained disseminated and some associated elements need to separate; they can be continuously ground to a certain grain size. Finely ground before try to be discarded in the case of coarse level part veinstone or selects some of concentrate.
(2) Foreign manganese ore resources are concentrated, so the mill scale is generally relatively large.
(3) high-quality products. The foreign ore manganese ore is of high grade manganese beneficiation effect and high quality products. South Africa manganese ore only by crushing, washing, product manganese content can be 40-48%; Australia average selected taste is 33%, concentrate manganese content of 42-50%; Gabon manganese ore after heavy media ore beneficiation, concentrate manganese is of 49 -50%.
(4) High degree of automation.
(5) Beneficiation processes and equipment are continually to be improved and updated to improve the quality and quantity of concentrate.
(6) products deep processing: there is a new development trend of commodity ore further deep processing of manganese products instead of ore exports to increase economic efficiency.
