Description

A kind of tin-lead soldering collecting agent and its application
Technical field
The present invention relates to a kind of mineral floating collecting agent, and in particular to a kind of collecting agent for for tin-lead soldering separate, category In cassiterite mineral floating technical field.
Background technology
Tin is human being's production and a kind of indispensable important meals of life, is also to find and use earliest in human history One of metal, because it has the advantages that fusing point is low, corrosion-resistant and malleable other metallicities, in all fields of national economy It is widely used;Current countries in the world constantly increase to the demand of tin, and the level of consumption of tin has turned into one National Industrial hair of measurement One of index of exhibition level.Cassiterite stanniferous 78.6%, is most common tin mineral, is also the topmost ore mineral of tin.I State's Tin Resources enrich, and distributed areas are wide.Mainly based on primary deposit, wherein Associated Constituents are more.The main work of cassiterite preservation Industry type:In cassiterite-Rare Metal Deposit, cassiterite is close with columbite, tantalite, beryl, calcite, quartzy symbiosis; In residual slide rock sandy cofferdam, the densification symbiosis of cassiterite and oxide mineral;In cassiterite-Sulphide Ore, cassiterite and calcite, stone The symbiosis such as English, wolframite, galena, pyrite, disseminated grain size is thin.Therefore, cassiterite is difficult with other mineral disaggregations, in technique often Need fine grinding.Meanwhile, cassiterite density is big, and gravity treatment is traditional ore-dressing technique that cassiterite is reclaimed, the method low cost, environmentally friendly. But cassiterite is crisp frangible, and grinding process was susceptible to crushing, while with the passage of recovery time, the tin in milling ore Stone granularity constantly attenuates, and when micro fine particle is reclaimed using reselecting method, the tin rate of recovery is low, and effective recovery lower limit of flotation grain Spend, important method for as micro fine particle effectively reclaiming one of low compared with gravity treatment.Additionally, often containing various oxidations in tin ore Mineral, the presence of such as quartz and calcite mineral directly affects the raising of Tin concentrate quality, can effectively be realized using flotation Cassiterite separation therewith.
The development of Flotation of Cassiterite collecting agent is the key for promoting micro fine particle flotation development.Tin-lead soldering collecting agent amounts to Up to as many as over one hundred kind, aliphatic acid, arsenic acid, alkyl sulfate, alkyl sulfosuccinamate and alkyl phosphorous acid can be divided into Several major classes such as ester (alkyl phosphoric acid).Fatty acid collecting agent collecting is cheap, nontoxic, collecting ability strong, but to association gangue Mineral quartz, calcite poor selectivity;Arsenic acid selectivity is strong, but environmental pollution is serious, be detrimental to health;Alkylsurfuric acid Salt is stronger to the collecting ability of cassiterite mineral, but such collecting agent is to Ca2+、Fe2+Sensitivity, and it is just effective only under acid condition, It is difficult to industrial applications;Alkyl sulfosuccinamate collecting ability very strong, consumption is less, cheap, nontoxic nothing Evil, it is short with mineral action time, and to coarse grain tin-lead soldering effect preferably, but equally exist to quartz, calcite poor selectivity Shortcoming;It is worth it is emphasized that short-chain alkyl phosphite ester and short-chain alkyl phosphoric acid are isomers, existing report two Person may be used to tin-lead soldering collecting, but both are weaker, it is necessary to add substantial amounts of activator to the collecting ability of cassiterite (heavy metal ion) is used cooperatively, and not only increased industrial cost but also has been caused environmental disruption.Although sub- by increasing short-chain alkyl The carbochain of phosphate and short-chain alkyl phosphoric acid, can to a certain extent strengthen the collecting ability of collecting agent, but its dissolubility Can be substantially reduced again with selectivity, and alkyl phosphite and alkyl phosphoric acid are all in the presence of extremely quick to iron, copper ion in ore pulp The problem of sense, causes its collecting ability to cassiterite and selectivity cannot be guaranteed.
