The main points that the raw ore preliminary treatment will be held are: usually contain a large amount of gangue minerals in the copper nickel thing, and these gangue mineral argillizations are serious, natural floatability is better, easily enters in the flotation froth, affects the flotation of copper nickel thing.Therefore raw ore need to be carried out preliminary treatment, adopt 2
#Oil carries out the desliming operation.And 2
#Oil consumption must control well, consumption very little, desliming is incomplete; Consumption is too many, and copper, nickel mineral loss are seriously.
The main points of selecting the copper circulation to hold are:
Because the suppressed rear activation difficulty of nickel mineral, cause nickel recovery on the low side, so in the cu-ni sulphide ore floatation separation process, should nickel mineral not suppressed, simultaneously in the copper mineral flotation process, if the nickel mineral of introducing can increase again the difficulty that copper nickel separates too much, so the selection of collector of copper sulfides is the key of test in floating copper process.The Z-200 collecting agent has shown high selective power in selecting the copper process, the recovery of copper rate is also higher simultaneously, and the content of nickel is minimum in the copper rough concentrate, and follow-up copper nickel is separated the critical effect of having played.Therefore, employing is done copper mineral collecting agent, 2 to the Z-200 that copper has high selectivity
#Oil carries out the Floatation of Copper mineral as foaming agent.For avoiding the suppressed rear activation difficulty of nickel mineral, nickel mineral is not suppressed, but the consumption of Z-200 must be got hold of in the floating copper process.Consumption is little, and copper recovery is inadequate; Consumption is large, and the content of nickel increases, and increases the pressure that copper nickel separates, so will control in right amount the consumption of Z-200.
Copper nickel separates the main points that will hold and is: will first copper nickel bulk concentrate be regrinded for copper, the nickel adhesion is fine and close, disseminated grain size is trickle copper nickel stone, promote the abundant monomer dissociation of copper nickel thing.The rear adding activated carbon reagent removal of regrinding adopts lime and sodium hydrogensulfite to make the nickel mineral inhibitor, and butyl xanthate is made the copper mineral collecting agent, presses down the floating copper copper nickel of nickel and separates.Wherein copper nickel bulk concentrate again the consumption of grinding rate and activated carbon be crucial, whether fully the selection of grinding rate has determined copper nickel thing monomer dissociation again, and the quality of activated carbon reagent removal effect directly affects the separation of copper nickel, because the activated carbon consumption is too little, then reagent removal is incomplete; Consumption is too large, does not then adsorb saturated part activated carbon and can adsorb collecting agent and foaming agent, causes collecting agent and foaming agent consumption to increase, affects copper, nickel separates.
The main points of selecting nickel circulation to hold are: because that the gangue mineral in the ore has alkalescence is higher, specific area is huge, the characteristics such as high adsorption capacity, easily being adsorbed on nickel mineral surface affect the flotation of nickel mineral, so adopt sulfuric acid adjusting slurry pH to carry out the activated ni mineral about 5～6 during the flotation nickel mineral.
The present invention adopts Z-200 to make copper mineral collecting agent Floatation of Copper mineral, regrind after copper nickel rough concentrate is selected, realize that copper, nickel monomer fully dissociate, adopt afterwards activated carbon to carry out reagent removal, adding lime presses down the floating copper copper nickel of nickel with the sodium hydrogensulfite composite restrainer and separates, the chats that copper nickel is selected and copper tail merge, and adopt sulfuric acid, copper sulphate to make activator, butyl ammonium aerofloat and Mac-12
#Make collecting agent flotation another part nickel mineral, realized that the efficient flotation separation of complicated low-grade fine-grained disseminated grain cu-ni sulphide ore separates.
The copper mineral collecting agent Z-200 that the present invention adopts is to the nickel mineral poor selectivity, introducing nickel mineral that can be less is in copper concentrate, and (lime+sodium hydrogensulfite) combination medicament can carry out strong inhibition to nickel mineral, the copper tail is independent flotation another part nickel mineral again, the copper nickel FLOTATION SEPARATION of complicated low-grade fine-grained disseminated grain cu-ni sulphide ore is become easily carry out; Realized the separation of copper, nickel mineral, output qualified copper, the single concentrate of nickel; The purpose mineral are fast thorough emersion in flotation circuit separately, has avoided the vicious circle of chats and the unnecessary consumption of floating agent, meets energy-conservation needs; The floating agent high-efficiency cleaning that adopts meets the requirement of cleaner production; Stable technical process, to the ore strong adaptability, Seasonal Temperature Difference is little to Index Influence.
Method of the present invention can be floated the floatation separation process strong adaptability, not only copper, the nickel mineral of the low-grade fine-grained disseminated grain of recyclable complexity, and can realize the FLOTATION SEPARATION of copper, nickel mineral, significantly improved quality and the rate of recovery of copper, nickel ore concentrate, improved the level of profitability, and do not pollute natural environment.A kind of economy, simple, applicable, controllability is strong, good separating effect, processing cost a kind of low-grade fine-grained disseminated grain copper nickel stone iso flotability flotation separation process scheme low, applied widely.
