褐铁矿和锰矿难于浮选的主要原因之一,是由于这些矿物的比表面大和在选矿准备和浮选过程中形成大量微细颗粒。同时,由于褐铁矿的储量和许多矿床锰矿石的重选矿泥产率大,因此对研究工作者提出了寻求浮选这些产物途径的任务。
One of the main reasons why limonite and manganese ore are difficult to flotation is due to the large specific surface area of these minerals and the formation of large numbers of fine particles during mineral preparation and flotation processes. At the same time, research workers are tasked with seeking ways to flotate these products because of the large reserves of limonite and the re-election sludge produced in many deposits of manganese ore.
