The Mining Measures of Placer Mine in Ore Beneficiation

KDE - Jul 28 2014
not answered
Question:Weathering and talus deposits accumulate brown iron ore, clay more commonly used method of gravity separation, that is, after washing with a jig and a centrifugal concentrator machine sorting, you can use the gravity separation - intensity magnetic separation processes.multi-metal-containing weakly magnetic iron ore, mainly hydrothermal and sedimentary phosphorus or vulcanized Wo of hematite iron ore or turbot. Such ores typically use the gravity separation, flotation, strong magnetic separation or joint process to recycle iron minerals, phosphorus or sulfur recovery use flotation process. Hydrothermal apatite-containing hematite iron ore and copper sulfide flotation methods can be used.

Collected sand processing equipment need to go through screening, in the gold mining ship, stone crusher and screening operations together when done inside the cylindrical sieve. Cylinder Screen built with intermittent spiral angle. Operation, the cylindrical sieve pressure washing should not be less than 35 kPa, fixed processing plant on land, set for crushing and washing deposit screening. Then is off the mud, mud off the production equipment used for a variety of sizes from mud bucket, while allowing the material chute with gold grain width, and processing capacity, and thus not before sorting chute off the mud.

Coarse grain and highly coarse grain( 20mm) iron ore gravity separation commonly use dense medium or jigging beneficiation; center to fine grain ore use spiral concentrator,shaker,sector chute and centrifugal separator of gravity separation.Coarse and fine iron ore strong magnetic separator commonly use dry reaction roller strong magnetic separation; fine iron ore commonly use reaction medium strong magnetic separation. At present,as fine iron ore strong magnetic separation concentrate grade is not high,gravity unit processing capacity is low, so compose strong magnetic-gravity separation unite process,use strong magnetic separation to abandon a large number of qualified tailings,then gravity separation process strong magnetic concentrate, to improve grade.
