选矿学英语(名词解释)

矿物：Existing in the earth's crust of natural compounds and a few natural elements, have relatively fixed chemical composition and properties.矿石：All the minerals in the earth's crust natural aggregation, in modern technology level of economic conditions, can with the industrial scale to extract the national economy required metal or other mineral products is the ore.品位：Refers to the ore elements or compounds useful it the percentage of content、、、Ore grade unit volume or unit weight to ore useful components or valuable mineral content.精矿品位: Concentrate the content of the main useful components says concentrate grade.尾矿品位: Tailings of main content of useful components called tailings grade.回收率：Refers to concentrate the metal (useful components) the amount and undressed ore metal (useful components) number of percentage精矿：Concentrate is dressing in one of the products of the sorting operation, is one of the highest content of the target useful component parts.尾矿：The homework in dressing sorting one of the products, the products in this work, the useful ingredient content of minimum.中矿：Between concentrate grade and tailings between, the need to further processing of products processing.富集比：Set than (enrichment ratio) concentrate grade and gives the ore grade than, say again than rich deposits.选矿比：Refers to the weight and in the crude ore concentrate of the weight of the elected than, or an average of one ton elected to concentrate the undressedore weight.产率：In beneficiation process flow, a product of the weight of the percentage of the crude ore in weight.重选：By sorting by mineral grains relative density and grain size, between the shape of the differences and their in medium (air, water or other relative density large liquid) movement rate and the direction of different, make separate processing method.磁选：Refers to the uneven in magnetic field, use different mineral between the difference at the separation of magnetic minerals choose don't method.浮选：Flotation is according to the mineral grains chemical and physical properties of different surface, from ore mineral separation useful technique.粒度：According to the material through and couldn't get through the sieve pores, according to the material into different level of particle size of homework.粒级：In some classification methods (such as the screening) will size range of particle swarm into wide ore size range of narrow several levels, these levels called grain grade.破碎比：The crusher is broken the size of materials and broken than after the ratio of the particle size. It said after the extent of raw material brokendecrease.选矿效率：In the process of mineral processing said useful mineral or metal ore concentrate the growth of the best and the false under the condition ofgrowth than筛分：According to the material through and couldn't get through the sieve pores, according to the material into different level of particle size of homework.分级：According to solid particle size for different with different subsidence in medium speed principle, particle group is divided into two or more grain size level of process.筛析：According to the particle size of the screen with classification method, known weight materials in size screen hole in a set of diminishing in a sieve, screen move after certain hours, and the material according to the size of theparticles were in each layer on a sieve, divided into several levels.解离：Borrow broken or ground effect, make the symbiosis between the components of the monomer separation phenomenon.解离度：A solution called from degrees, is the mineral monomer disintegrate particles with the number of particles of the mineral even had particles number andthe mineral of particles from the number of particles of monomer solutionto the ratio of the单体解离：The composition of the ore mineral separation of each other, become monomer disintegrate网目：The so-called mesh is 2.54 cm (1 inch) in length screen hole number, and referred to as "the eyebrows.捕收剂：Variable mineral surface hydrophobicity, make the phytoplankton ore lands on the bubbles of flotation reagents.活化剂：Change the inhibition of the surface mine hydrophobic flotation agents.起泡剂：Promote have bubbles, maintain foam stability of flotation agents.抑制剂：Reduce some of the ore surface hydrophobicity, make them not easy to float to the top of the flotation agents.调整剂：Adjust the coal slurry and the nature of the surface mine grain, improve the efficiency of a flotation agents or eliminate harmful impurities in therole of the flotation agents.。
