Description

Laboratory heavy mineral enrichment and separator

Technical Field

The utility model relates to a mineral separator especially relates to a heavy mineral enrichment and separator in laboratory.

Background

Heavy minerals are ground source clastic minerals with a specific gravity greater than 2.86, which are usually secondary minerals in parent rock. The mechanical property and the chemical property are stable, and the method has important significance in the aspects of deducing the composition of land source areas and parent rocks, dividing contrastive strata and the like. The content of the heavy mineral in the sedimentary rock is generally less than 1%, and the clastic substances formed by weathering and destruction of the rock or the ore are relatively enriched in sedimentary sand grains formed after carrying and sorting, but also contain a large amount of light minerals, so that the heavy minerals need to be sorted from the rock and the sediment to effectively analyze the heavy minerals.

The separation of heavy minerals generally comprises methods such as artificial elutriation, blowing, heavy liquid separation and the like. The blowing method is affected by factors such as the proficiency of operation, the particle size and the difference in specific gravity, and is not widely used in separation work. Heavy liquid is needed in the heavy liquid separation method, the common heavy liquid has large smell, the cheap heavy liquid generally has certain toxicity, the sodium tungstate is nontoxic and tasteless, but the price is high, and the cost is high when the sodium tungstate is used in production. The manual elutriation method adopts an elutriation plate or a mechanical elutriation method in water, so that the cost is low, and a tool for manual elutriation is simpler and is more suitable for field operation. The mechanical elutriation is an elutriation machine manufactured according to the bumping and shaking principle of manual elutriation, a shaking table is generally adopted for heavy mineral separation, the shaking table achieves the purpose of heavy mineral separation and light mineral separation through front-back or left-right asymmetric reciprocating motion, and the front-back or left-right asymmetric reciprocating motion of the shaking table is combined to achieve fine elutriation of heavy minerals. At present, the sand ore shaking table which is widely applied is provided with parallel grooves carved on the surface of the shaking table, the shaking table is parallel to the grooves and does asymmetric reciprocating motion, and light and heavy minerals are separated. A vibration/wriggling chute for further fine panning adopts the bed surface of being carved with parallel slot, and the slot slope becomes certain angle, and the sample is under the effect of rivers effort, frictional force and gravity isokinetic force with the groove face, and the great mineral of proportion stays in the groove, the separation of mainly used gold at present, because the groove shape and degree of depth make wash comparatively difficult, the loss is higher. The equipment is large-scale equipment used for mines, the daily average handling capacity is large, the general sample amount of geological samples is small, the lowest amount and precision of the samples which can be processed by the equipment on the market at present cannot meet the requirement of geological sample processing, and the equipment is large in size, high in noise and not suitable for being used in laboratories.
