The Effect of Slurry Concentration on Mining Iron Ore

When choosing iron ore mining process, iron ore mining company is a very important index.And for mining iron ore, iron ore mining machines can directly reflect the recovery rate. since Xinhai is a large iron ore mining company with over decades, here is a brief introduction of mining iron ore.

The slurry concentration refers to the content of the solid material in the slurry, usually represented by wg which is used to define the ratio of liquid to solid or solid mass fraction. The slurry concentration is one of the most important factors which affect mining iron ore. It will affect the charging degree of iron ore slurry, the residence time in of iron ore slurry in the flotation cell, reagent system and the adhesion process of bubble particle.

Firstly, the inflatable performance of flotation cell changes with the iron ore slurry concentration. Whether the slurry is too thick or too thin will make the inflation situation worse, thus affecting the iron ore flotation recovery rate and flotation time.

Secondly, under the same dosage, if the slurry density increases, the reagent concentration also will increases, which will be conducive to mining iron ore so as to reduce the drug dosage and the reagent cost.

Thirdly, with the increase of slurry concentration, the residence time of slurry in flotation cell will be prolonged and this is conducive to the improvement of recovery rate. If the flotation time constant, with the increase of the slurry concentration, the productivity of mining iron ore increases.

Fourthly, In a certain range, with the increase of slurry concentration，buoyant force lift, this is conducive to the flotation of coarse iron ore; while if the slurry concentration is too thin, the result also will be deteriorated. For fine particle flotation, with the increase of slurry concentration, fine-grained hydrophilic iron ore will affect the reverse flotation.

In short, increasing slurry density is beneficial to mining iron ore, and the water and power consumption of per ton of material is less. General principles of iron ore slurry concentration are coarse grain with high concentration, fine with low concentration; roughing by high concentration, featured by low concentration. The range of iron ore concentration of reverse flotation is generally 22~40%.
