subject: Re-election Used To Recover Weak Magnetic Iron [print this page] Re-election used to recover weak magnetic iron
China's iron ore characteristics:
lean ore occupies big proportion. the iron content below 45% occupies of the total reserves of 86%;
red ore occupies big proportion., a variety of weakly magnetic ores occupies of about 65% of total reserves;
composite ore associated with many other useful components occupies big proportion, accounting for about 2/3 of the reserves.
And useful minerals in the majority of ore were fine as well as micro-fine disseminated required pulverized to 200 mesh in order to achieve the basic accounting for about 80%monomer dissociation. These characteristics of China's iron ore beneficiation extremely difficult task.
Depending on the mineral composition and properties of the iron ore deal with a variety of methods. The main ore containing magnetite with a simple and effective dressing method of weak magnetic, which still contains a weakly magnetic iron minerals hematite,can be used to re-election method (gravity dressing) supplementary recovery.
The main ore containing hematite (a red ore and the like) can be magnetized roasting -low intensity magnetic separation, flotation, or re-election law.
Roasting has 10 years of production history in China, process maturity, technical indicators, but this method of investment in infrastructure and equipment maintenancecapacity, and often limited by the gas supply conditions. Flotation equipment (flotation machine) processing capacity, the stability of the production targets, is an effective method for processing fine-grained disseminated hematite.
The disadvantage is that the consumption of expensive flotation reagent and rare high-quality concentrates, dehydration is also more difficult to concentrate.
Deal with magnetic - red mixed ores using magnetic - floating or magnetic - heavy jointprocess. For other kinds of iron ore, like limonite, siderite (both belong to the red ore),vanadium and titanium magnetite ore in accordance with the mineral composition of thewashing re-election, roasting or magnetic - re-election - the electric treatment.
The re-election law is the basic method to deal with coarse-grained hematite, both technical and economic indicators can and other beneficiation methods. Fine-grained and micro-fine iron ore re-election is also a new development in recent years.
