Abstract
The present invention relates to a method for preparing rock ore gold testing standard samples used for verifying the accuracy of gold contents in measured rock ores, namely a powder standard liquid permeating and condensing method. The present invention is characterized in that the powder standard liquid permeating and condensing method comprises: mixing empty core powder with a gold solution. The present invention has the following advantages: compared with the conventionally used gold powder mixing methods, the present invention increases the efficiency by hundreds of times, reduces the cost by hundreds of times and has higher uniformity (reaching 99.5%) of the gold content in a standard sample; the method belongs to a physical method which is capable of avoiding or reducing aliquation or loss resulted from substance denaturation caused by chemical methods and directly observing the content of elements; multiple means are not adopted to determine the value of the standard sample; the method of the present invention is simple and convenient.
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 gold content accuracy in the past: the one, get natural gold ore processing preparation, and adopt hand breaking, join ore deposit, dilute, mix and make.Test through multiple use for laboratory several different methods of weighing into again.Last definite value distribution is used. and its workload of standard specimen of preparation is large like this, and efficiency is low, and cost is high.And because pressed powder blending is extremely evenly difficult or have a strong impact on its uniformity coefficient and stability because there is flour gold " precipitating ".Totally two, according to reports: be with the acid solution that mixes the required trace element of positive silicon tetrem fat and doping.Then make potpourri chemically reactive become colloid.Under violent stirring, make potpourri hydrolysis form uniform gel, dry rear calcination is pulverized and is obtained required test standard specimen.But exist in chemical reaction. the segregation that material metamorphosis causes and loss, bring difficulty to standard specimen definite value.The 3rd, metallurgical industry adopts under metal melting and is uniformly mixed doping known substance.Thereby obtain solid metallurgy sampler.This method conditional request is high.Uniformity coefficient is also undesirable.Gold only can be made platform gold with a few metals.
Task of the present invention is to provide that a kind of work efficiency is high, and cost is low, easy, can avoid or reduce the letter that chemical reaction and the metamorphosis of mechanical processing process material causes and pray and lose.Good stability, uniformity coefficient is high, and intuitively method-powder mark liquid of the preparation rock gold mine of standard specimen definite value test standard specimen oozes solidifying method.
Task of the present invention completes in the following manner: select the same or analogous empty ore deposit in component and alloy rock ore deposit, first by broken empty breeze.The proof gold that should add, with arriving required volume with distilled water diluting after aqua regia dissolution, is then mixed empty breeze end with gold solution, drying, pulverizes and just makes rock-ore gold test standard specimen.
The advantage of invention: the one, than the high hundreds of times of gold mine powder fusion method efficiency of always continuing to use.Cost is its hundreds of/mono-, and standard specimen contains golden uniformity coefficient up to more than 99.5%; The 2nd, this law is directly to mix solidifyingly with matrix and mark liquid, can avoid or reduce general chemistry or machining and the material metamorphosis that causes causes partially prays and lose, and constituent content directly perceived, and not needing to adopt multiple means is standard specimen definite value; The 3rd, easy, can prepare the golden standard specimen of different lithology component and each content series.
Indefiniteness embodiment of the present invention:
By the same or analogous empty ore deposit of component and tested alloy rock ore deposit, be ground into 200 object powder, by the auspicious content of set mark and empty breeze weight, can draw use
by aqua regia dissolution for proof gold (1:1), then use distilled water diluting.The distillation water yield=excreting dampness used is than the empty breeze weight of (O.24～O.27) x: by the alloy dilution just having prepared in the container of chemical stabilization.The i.e. mixed platform of speed and empty breeze, with bobbing machine or with being manually squeezed into rhythmically gel.Dry or dry auspicious gelatinous mark, then after crushing and mixing, being placed in 105～llO DEG C of dry doubling and keeping 2 hours.Take out cooling.Pulverize, mix and just become rock-ore gold test standard specimen.
Claims (2)
1. prepare the method for the rock-ore gold test standard specimen of verification rock-ore gold content accuracy with oozing solidifying method, it is characterized in that comprising the steps; Select component with containing empty ore deposit roughly the same, banket ore deposit, grinding mixes that to make empty ore deposit base thing for subsequent use, chloroazotic acid proof gold for that should add (or with other strong acid oxidizer) dissolving and arrive required volume with distilled water diluting; Then a certain amount of empty breeze end is mixed with gold solution, drying, pulverize, mix, just make rock-ore gold test standard specimen.
2. method according to claim 1. it is characterized in that described empty breeze to be milled to 200 meshes, mix and make empty ore deposit base thing, then according to the standard specimen gold content of the consumption of described empty breeze and the preparation that requires, obtain according to the following formula required pure gold consumption:
With gold amount (gram)=standard specimen gold content (gram/gram) × empty breeze weight (gram)
Then by described golden with aqua regia dissolution (1: 1). diluted with distilled water again. required distilled water consumption is calculated as follows:
Distilled water consumption (ml)=excreting dampness is than (0.24-0.27) × empty ore deposit
Powder weight (gram)
By just prepared containing golden dilution in the container of chemical stabilization. speed and empty ore deposit mix. vibrate or make gel with the excreting dampness breeze of manually extruding rhythmically with bobbing machine, gelatinous standard specimen is dried or is dried. crush again, after mixing 105-110 DEG C of oven dry. and keep 2 hours. take out cooling, pulverize, mix. packing is rock-ore gold test standard specimen.
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 gold content accuracy in the past: the one, get natural gold ore processing preparation, and adopt hand breaking, join ore deposit, dilute, mix and make. again through multiple authoritative use for laboratory several different methods tests. last definite value distribution is used.Its workload of standard specimen of preparation is large like this. and efficiency is low. and cost is high, and because pressed powder blending is extremely evenly difficult or have a strong impact on its uniformity coefficient and stability because there is flour gold " precipitating ". they are two years old. according to reports: be with the acid solution that mixes the positive silicon tetrem fat trace element required with doping. and then make potpourri chemically reactive become colloid. under violent stirring, make potpourri hydrolysis form uniform gel, after dry, calcination is pulverized and is obtained required test standard specimen. but exist in chemical reaction, the segregation that material metamorphosis causes and loss, bring difficulty to standard specimen definite value. the 3rd, metallurgical industry adopts under metal melting and is uniformly mixed doping known substance, thereby obtaining solid metallurgy sampler. this method conditional request is high, uniformity coefficient is also undesirable, gold only can be made alloy with a few metals.
