Description
Technical field
The invention belongs to metallurgical and analytical chemistry field, and in particular to one kind is used to directly particle diameter, composition differ greatly
Copper cobalt red alloy and bidery metal quickly mix, the method for sample preparation.
Background technology
China is the country of a cobalt resource famine, in recent years, with the rapid development of economy, especially lithium battery
Industry is developed rapidly, and the demand to cobalt is increasing.Cobalt in most cases all with other elements association, copper cobalt ore is cobalt
Main source, for world wide, Africa it is especially the most famous with the copper and cobalt resources of Congo (Congo-Kinshasa), Zambia, its cobalt storage
Measure the half close to world's cobalt resource amount.At present in Africa, especially the Congo is golden, and the smelting process of copper cobalt ore is except wet processing
Outside, electric furnace reduction melting is also a kind of main technique for handling copper cobalt ore, and its product is copper-cobalt alloy.The low alloy of the high cobalt of cupric
Referred to as red alloy, and the alloy of the low copper of high cobalt is referred to as bidery metal.Co pricing mode is in LMB cobalts official in current copper-cobalt alloy
A coefficient at a discount is multiplied by basis of price, and Cu pricing mode is then more special in alloy, its price is by the copper in alloy
Cobalt is than determining, copper cobalt is than higher, and the valuation coefficient of copper is higher, conversely then lower.Based on this reason, to improve Cu in bidery metal
Valuate coefficient, bidery metal and red alloy are carried out into mixing can yet be regarded as a kind of good method.However, the white conjunction that different manufacturers are produced
It is golden to differ greatly with red alloying pellet, composition, thus bring and how quickly to mix, sample and a series of problems, such as sample preparation.
The content of the invention
It is used for high-copper low cobalt powdery alloy and the low copper particle shape alloy mixing sample preparation of high cobalt the purpose of the present invention is to propose to one kind
Method, solves the problem of red bidery metal copper cobalt ratio is different, improves the valuation coefficient of Cu in bidery metal.
The technical scheme is that：One kind is applied to the red alloy of high-copper low cobalt powdery and mixed with the low copper particle shape bidery metal of high cobalt
Close method for making sample, it is characterised in that：Device therefor includes spade, scraper, cuttage, double-roll crusher, grinder, reduction device, 1
Mm sieve；Specifically include following steps：
Step 1: the different red alloy of different-grain diameter, copper cobalt content, bidery metal are mixed, one is kept during operation
The order of the red spade bidery metal of alloy one of spade, is pre-mixed；
Step 2: the red of premixing, bidery metal are carried out turning over shovel mixing 3-5 times by scraper, final alloy piles three
Prismatic；
Step 3: mixed four faces of alloy heap are rule from bottom to top every 50cm-80cm；Then from alloy heap
Top starts, and is sampled in each region every 50cm with the surface of the vertical alloy heap of cuttage, successively around four, alloy heap
Face carries out grid sampling and taken until all；
Step 4: the alloy sample that cuttage is taken out crosses 1mm sieves first, oversize directly enters double-roll crusher and broken
It is broken；Then the alloy after will be broken crosses 1mm sieves again, and screenings is directly mixed in sample heap, and the oversize that can not partly sieve enters
Grinder be ground it is broken, grinding 3-5min after, the powdery alloy after grinding is mixed into sample heap；
Step 5: mix institute's sample thief for all sieving by 1mm with spade 6-8 times, uniformly after sample heap is entered into division
Device carries out continuously point sample, untill final alloy sample remains 3-5kg, and alloy sample packing is sealed up for safekeeping.
Beneficial effect：The present invention can efficiently realize that the red bidery metal of different-grain diameter, heterogeneity quickly mixes sample preparation, take sample preparation
Speed is fast, representative good, and simple to operate, cost is low, be easy to industrialized production, improves the valuation coefficient of Cu in bidery metal.Sample
Product are representative strong after making, the characteristics of uniformity is good, and the present invention is simple to operate, and floor space is small, it is easy to extensive work
Industry application.
Brief description of the drawings

Fig. 2 has mixed the sample heap schematic diagram after material for the present invention.
Embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the present invention's
Embodiment is described in further detail.
The present invention provides a kind of red alloy of high-copper low cobalt powdery and the low copper particle of high cobalt differed greatly suitable for particle, composition
The method that shape bidery metal quickly mixes sample preparation, its device therefor include spade, scraper, cuttage, double-roll crusher, grinder,
Reduction device, 1 mm sieve；Specifically include following steps：
Step 1: the different red alloy of different-grain diameter, copper cobalt content, bidery metal are mixed, during operation substantially
The order of the red spade bidery metal of alloy one of a spade is kept, is pre-mixed；
Step 2: the red of premixing, bidery metal are carried out turning over shovel mixing 3-5 times by scraper, final alloy heap is in three
Prismatic；
Step 3: by mixed four faces of alloy heap from bottom to top every 50cm-80cm line, wherein alloy heap two
The line of individual side is parallel to each other, and the line of two end faces is drawn by top；Then since at the top of alloy heap, each region
