Description
Technical field
The invention belongs to the mineral floating technical field, relate to a kind of floating agent for gold ore flotation, particularly a kind of refractory gold ore collecting agent.
Background technology
The enrichment method of gold mineral is except leaching, and majority still adopts method for floating to reclaim gold mineral when selecting factory to produce.At present gold mineral there is the collecting agent of better collecting effect that puratized agricultural spray black powder, butyl ammonium aerofloat are arranged, catches the floating agents such as Jin Ling, Y-89, M16, QF, the conventional flotation medicament is stronger to the collecting ability of gold mineral, but selectively relatively poor, exist the problem that gold recovery is low, the index fluctuation is large, flotation effect is undesirable, resource utilization is low, difficult realization mineral resources economic, Efficient Development utilization.
Research, exploitation and the application of novel, the efficient combined flotation medicament of carrying out around improving golden mineral processing index in recent years, have obtained greater advance.Research and application facet at the new high-efficiency medicament are especially outstanding with improved chemical.The medicament modification comprises: introduce energy improvement and strengthen the force of reagents and mineral and show interactional other active group in existing medicament; Developing individual water-soluble huge legendary turtle closes or the complexing medicament; Selection has two kinds and combination and the mixed reagent of various medicaments of different activities and function.Quartz content is high in the carbonaceous quartzite type gold ore, and the gold mineral disseminated grain size is thin, distribute to disperse very much, and the part gold mineral is wrapped in gangue mineral and other mineral with the microfine form, is more difficult to get effective recovery; Part Carbonaceous matter adsorpting formulation in floatation process in the ore affects medicament to the collecting of gold mineral, causes the to a certain degree loss of amount of metal; Cause actual ore dressing effect unsatisfactory, Gold Concentrate under Normal Pressure grade and the rate of recovery are on the low side, and the waste mining deposits brings loss for enterprise and society.
Summary of the invention
The purpose of this invention is to provide a kind of refractory gold ore collecting agent for the flotation of carbonaceous quartzite type gold ore, this ore that fully dissociates, collecting ability is strong, improves Gold Concentrate under Normal Pressure grade and the rate of recovery.
For achieving the above object, the technical scheme that the present invention takes is: a kind of refractory gold ore collecting agent, and by weight by 20～40 parts of sulphur nitrogen nitrile esters, 25
#10～20 parts of black powder, 30～60 parts of liquid butyl ammonium aerofloats and 5～15 parts of compositions of black powder acid.
Further preferred version is: a kind of refractory gold ore collecting agent, and by weight by 30 parts of sulphur nitrogen nitrile esters, 25
#15 parts of black powder, 45 parts of liquid butyl ammonium aerofloats and 10 parts of compositions of black powder acid.
Collecting agent of the present invention has collecting and foaming double attribute, can give full play to the cooperative effect of each component during flotation, flotation phenomenon and result of the test show, compare with existing conventional collecting agent, the present invention has selectively good, collecting ability is strong, flotation froth is stable, mineral swim fireballing characteristics, but Effective Raise concentrate grade and the rate of recovery.
The specific embodiment
Below principle of the present invention and feature are described, institute only gives an actual example and to be used for explanation the present invention, is not be used to limiting scope of the present invention.
For carbonaceous quartzite type gold ore, in order to improve Gold Concentrate under Normal Pressure grade and the rate of recovery, reduce the loss of gold, the invention provides a kind of gold mine collecting agent for this refractory gold ore flotation, formed by the raw material of following weight portion:
20～40 parts of sulphur nitrogen nitrile esters
25
#10～20 parts of black powder
30～60 parts of liquid butyl ammonium aerofloats
5～15 parts of black powder acid
The optimization formula of above-mentioned refractory gold ore collecting agent: sulphur nitrogen nitrile ester weight portion is 30 parts, 25
#The black powder weight portion is that 15 parts, liquid butyl ammonium aerofloat weight portion are that 45 parts, black powder acid weight portion are 10 parts.
The preparation of refractory gold ore collecting agent of the present invention: the sulphur nitrogen nitrile ester, 25 that will get by weight
#Black powder, liquid butyl ammonium aerofloat and black powder acid add in the stirred tank, mix 0.5～1 hour under the normal temperature and pressure, and get final product.
Sulphur nitrogen nitrile ester (ester-105) is a kind of collecting agent that has frothing capacity concurrently, is mainly used in sulphide ore, multi-metal sulfide stone and the flotation of association gold and silver such as copper, nickel; 25
#Black powder has collecting and foaming characteristic, can be used for the flotation of copper, lead, zinc, bismuth sulfide minerals, closes use with black powder acid, and the noble metals such as gold, silver are had preferably concentration effect; The liquid butyl ammonium aerofloat has preferably selective and foaming characteristic, can be under lower pH value condition, and floating gold, floating copper or floating plumbous.25
#Black powder has collecting and foaming characteristic, can be used for the flotation of copper, lead, zinc, bismuth sulfide minerals, is used in combination with black powder acid, and the noble metals such as gold, silver are had preferably concentration effect.Black powder acid is the dibutyl phosphordithiic acid, is a kind of acid intermediate product that generates in the synthetic butyl ammonium aerofloat process.In order further to improve gold recovery in the refractory gold ore, used black powder acid in the collecting agent of the present invention, experiment is found to add an amount of black powder acid, can improve gold recovery 2～3%.
Collecting agent of the present invention can be given full play to the cooperative effect of each component in floatation process, produce coadsorption, has promoted the concentration effect of collecting agent to gold mineral.Reason has two aspects: the one, and the inhomogeneities of the physicochemical properties that mineral surfaces causes in Cheng Kuang, process, they have different adsorption capacities to collecting agent of different nature, the sulphur nitrogen nitrile ester, 25 among the present invention
#Black powder has stronger collecting performance, and butyl ammonium aerofloat has selective preferably, and for the gold ore that adopts, in floatation process, they have brought into play suction-operated separately, have improved the hydrophobicity of mineral surfaces, thereby have improved flotation effect; The 2nd, the interaction between two or more collecting agents, the absorption of this class collecting agent tends to promote owing to a kind of existence of collecting agent the absorption of another kind or other medicament.Sulphur nitrogen nitrile ester among the present invention, butyl ammonium aerofloat, 25
#Black powder and black powder acid are used in combination, and except bringing into play different separately adsorption capacities, have also promoted each other the suction-operated of other medicament.
