Various beneficiation process description

2013-12-20

 Beneficiation process will vary according to differences between the types of ore , ore sorting the following is a common method of introduction:

Select iron : 1 , ore crushing ; 2 , grinding process ; 3 , sorting technology ; 4 , sintered pellet technology ;
 
Select Manganese : Mechanical election ( including beneficiation , screening , re-election , strong magnetic separation and flotation ) , and vice- set fire , chemical beneficiation method.
 
Select Chrome : Firstly jump titanium machine, shaker , spiral concentrator , centrifugal concentrator and sorting belt chute , the force of the water also sorting .
 
Vanadium titanium magnetite : is it after a period of grinding, a coarse , a fine , sweeping away the magnetic separation process to elect the magnetotail magnetic magnetite concentrate after performed .
 
COPPER : flotation , magnetic separation, re-election or hydrometallurgical methods and so on.
 
Select lead and zinc : general magnetic - floating , heavy - floating , heavy - Magnetic - Floating other joint beneficiation methods.
 
Choice of aluminum : general use hand-selected . Select aluminum equipment includes magnetic separator, ball mill , conveyor, magnetic roller, iron absorption , magnets, electromagnets and so on.
 
Select Nickel: 1 , flotation ; 2, using crushing, screening and other processes in advance to remove the differentiation of weak , low bulk nickel bedrock .
 
Select Cobalt : Average flotation .
 
Select tungsten : tungsten mineral divided by ore type wolframite and scheelite . Beneficiation methods are hand-selected , re-election , flotation , magnetic separation, electrostatic separation , and other methods .
 
Select the tin : gravity beneficiation beneficiation , flotation process .
 
Molybdenum : mainly flotation.
 
Select Mercury : There are hand-selected , re-election and flotation , which is widely used and most effective flotation .
 
Select Antimony : There are hand-selected , re-election , flotation and other methods.
 
Select platinum group : 1 , reasonable milling , using appropriate cyclone classification ; 2 , recoveries ;
 
With gold : gold in the ore content is very low, you need to extract gold ore crushing and grinding and beneficiation methods to separate the gold . Mainly re-election and flotation .
 
Select Silver : 1 , flotation ; 2 , a single flotation and floating - joint process re-election law , cyanidation of flotation , flotation which is most important.
 
Lithium , tantalum , niobium , beryllium election : Hand election law , flotation , chemical or chemical - combined flotation method, enthusiastic election law , election law radioactivity , grain float beneficiation method.
 
Strontium election : heavy stone lapis lazuli community beneficiation method most commonly used , the most common structure for the process to jigging - shaker as the main flow.
 
Selected rare earth metals : general use magnetic separation, flotation concentrate containing about 60% to get rare earth oxides
