Abstract
A kind ofly be used for verification and survey the compound method of the rock-ore gold test standard specimen of rock ore deposit gold content accuracy,---powder mark liquid oozes method with fixed attention, method is mixed with empty breeze and gold solution to it is characterized in that oozing with fixed attention by this powder mark liquid, its advantage: the one, improve hundreds of times than the bronze end fusion method efficient of always continuing to use, cost is reduced to its hundreds of/one, and standard specimen contains golden uniformity coefficient height, reaches 99.5%.The 2nd, our physical method owned by France can be avoided or reduces segregation and the loss that the material metamorphosis that causes with chemical method causes, and constituent content directly perceived, and need not adopt multiple means is the standard specimen definite value, and the 3rd, easy.
Description
The present invention relates to rock-ore gold test standard specimen compound method.
Be used for verification surveys the compound method of the test standard specimen of rock ore deposit gold content accuracy in the past: the one, adopt empty ore deposit and the gold allocated into is ground into powder respectively, then both stirring and evenly mixings, because the gold amount is few, empty ore deposit is many, mixed uniformity coefficient is poor, and big metalworking powdered difficulty, inefficiency, therefore, the standard specimen cost height of preparation.The 2nd, be method with the similar method preparation trace test standard specimen with fixed attention of oozing with even doping Sio2 powder, make the potpourri chemically reactive become colloid then with mixing the acid solution of tetraethyl silicate resin with the required trace element that mixes, under violent stirring, make the potpourri hydrolysis form even gel, after the drying gel pulverizing is obtained required test standard specimen, but exist in the chemical reaction, segregation that material metamorphosis causes and loss cause difficulty for the standard specimen definite value.The 3rd, metallurgical industry, thus adopting metal to dissolve down to mix the doping known substance obtains the solid metallurgy sampler.This method, the conditional request height, uniformity coefficient is also undesirable.
Task of the present invention provides a kind of work efficiency height, cost method-powder mark liquid low, easy, that can avoid or reduce material metamorphosis causes in the chemical reaction segregation and loss, preparation rock-ore gold test standard specimen that uniformity coefficient is high and oozes method with fixed attention.
Task of the present invention is finished in the following manner: choose component and contain same or analogous empty ore deposit, banket ore deposit, broken empty breeze, the gold that should add with aqua regia dissolution after with distilled water diluting to required volume, empty breeze end and gold solution mixing, drying, pulverizing just are mixed with rock-ore gold test standard specimen then.
Advantage of the present invention: the one, improve hundreds of times than the bronze always continued to use end fusion method efficient, cost is reduced to its hundreds of/one, and standard specimen contains golden uniformity coefficient height, reaches 99.5%.The 2nd, our physical method owned by France can be avoided or reduces segregation and the loss that the material metamorphosis that causes with chemical method causes, and constituent content directly perceived, and need not adopt multiple means is the standard specimen definite value.The 3rd, easy.
Non-limiting examples of the present invention:
With component and the tested same or analogous empty ore deposit, banket ore deposit that contains, be ground into the powder that granularity is 200 meshes, by known standard specimen gold content of making and empty breeze weight, can draw with golden weight=(g(Au))/(t(ton)) * the empty breeze of g(is heavy), the gold and the aqua regia dissolution (1: 1) of same weight are used distilled water diluting then, and the used distillation water yield (mL)=excreting dampness is than (0.24～0.27) * empty breeze weight (g).Timely and the empty breeze of golden dilution that contains that has just prepared is mixed, be placed on then in the container of chemical stabilization with the bobbing machine vibration or with manually have joint with gathering stranding be extruded into gel, gelatinous standard specimen is dried or dry, crush again behind the mixing, put electric dry oven oven dry and in 105 ℃～110 ℃, kept 2 hours, take out the cooling mixing and just become rock-ore gold test standard specimen.
Claims (2)
1, a kind ofly is used for compound method-powder mark liquid that verification surveys the rock-ore gold test standard specimen of rock ore deposit gold content accuracy and oozes method with fixed attention, method is to it is characterized in that oozing with fixed attention by this powder mark liquid: choose component and contain same or analogous empty ore deposit, banket ore deposit, broken empty breeze, the gold that should add with aqua regia dissolution after with distilled water diluting to required volume, empty breeze end and gold solution mixing, drying, pulverizing just are mixed with rock-ore gold test standard specimen then.
2, the powder mark liquid of preparation rock-ore gold test standard specimen according to claim 1 oozes method with fixed attention, method is to it is characterized in that oozing with fixed attention by powder mark liquid: with component and the tested same or analogous empty ore deposit of gold mine that contains, be ground into the powder that granularity is 200 meshes, by known standard specimen gold content of making and empty breeze weight, can draw with golden weight=(g(Au))/(t(ton)) * the empty breeze weight of g(), with the aqua regia dissolution (1: 1) of gold with same weight, use distilled water diluting then, the used distillation water yield (mL)=excreting dampness is than (0.24～0.27) * empty breeze weight (g), timely and the empty breeze of golden dilution that contains that has just prepared is mixed, be placed on then in the container of chemical stabilization with the bobbing machine vibration or with manually have joint with gathering stranding be extruded into gel, the gel standard specimen is dried or dry, crush again behind the mixing, put electric dry oven oven dry and in 105 ℃～110 ℃, kept 2 hours, take out the cooling mixing, just become rock-ore gold test standard specimen.
