General terminology for non-metallic mineral products
Non-metallic mineral products common terminology, the national standard (GB5463.1-85) provides as follows:
General terminology and definitions or meanings of metallurgical auxiliary raw materials minerals and special non-metallic mineral raw materials, applicable to non-metallic mineral product standardization and non-metallic mineral geological exploration, mineral production, processing, inspection, trade and scientific research, teaching, etc. field.
General term
(1) Non-metallic minerals are generally not used for the purpose of refining metals, but directly utilize their physical and chemical properties.
(2) Non-metallic minerals, mineral aggregates or aggregates mined from ore bodies that can be utilized under current technical and economic conditions.
(3) Non-metallic minerals except for metal minerals and fuel minerals, all available rock and natural non-metallic mineral resources.
(4) Non-metallic mineral products The general term for non-metallic mineral raw materials and rocks produced by mining, mineral processing or grinding processes.
(5) Minerals that can be utilized in mineral ore or mineral products.
(6) Minerals that are currently not available in gangue mineral ore or mineral products.
(7) Useful components of useful minerals or minerals that can be utilized.
(8) Ingredients that are adversely affected by the use or production process of ore or mineral products.
(9) The content of useful minerals or useful components in the ore grade per unit volume or unit weight of ore.
(10) The grade of ore graded according to the content of beneficial, hazardous components, physical properties and requirements for different industrial uses.
(11) The ore that has been mined from the mine and has not been processed.
(12) Products in which concentrates are enriched by minerals after sorting.
(13) Concentrate products obtained by hand picking ore concentrates after manual sorting.
(14) Concentrate products obtained after sorting of ore concentrate ore by ore dressing equipment.
(15) The tailings are selected from the ore and the remaining products after the concentrate and intermediate products.
(16) Block ore refers to massive ore or mineral products.
(17) Powder ore or mineral products formed by the formation of ore deposits or crushing during mining.
(18) Powder ore products with a certain fineness after crushing or grinding ore powder ore.
(19) The ratio of the yield of the beneficiation product produced in the process. It is usually expressed as a percentage of the ratio of the weight of the product to the weight of the selected ore.
(20) Recovery rate The ratio of useful ingredients recovered in the selection. It is usually expressed as a percentage of the weight of a useful ingredient in the beneficiation product to the weight of the same useful ingredient in the ore to be ore.
(21) The size of the block lump ore. Usually expressed as the average diameter or maximum length of a certain grade of lump ore.
(22) The thickness of the fine powder ore or ore fines.
(23) A general term for the degree of particle size of mineral or mineral products.
(24) Sieve amount The weight of the material remaining on the screen at the end of the screening. It is usually expressed as a percentage of the ratio of the weight of the sieve to the weight of the sieve material.
(25) Variety of minerals? a href='http://' target='_blank'> Vanadium female frame (12) reading (15) Mirror Mirror What is the value of devaluation?
(26) Classification of mineral products of the same variety according to their length, area, grain size and particle size distribution, weight, whiteness and other characteristic parameters.
(27) The quality characteristics of the mineral products meet the requirements of industrial technology and the overall characteristics of the physical and chemical properties and the degree of processing.
(28) Grade is the grade of the same variety of mineral products according to their quality, which meets the needs of industrial production.
(29) Product inspection The inspection and verification of the quality and quantity of mineral products according to certain standards.
2. Physical property terminology
(1) Appearance quality The external physical properties of non-metallic mineral products directly observed by the senses.
(2) Mineral color minerals and mineral aggregates are selected from natural light to absorb different wavelengths of light and then reflect or transmit a mixture of other residual wavelengths.
(3) degree of whiteness (brightness as a white powder sample of non-metallic minerals, superior grade magnesium oxide refers to the absolute reflectance of the standard white monochromatic light of a specific wavelength as a reference ratio, corresponding to a single wavelength display material whiteness The absolute reflectance of the surface of the sample plate measured by the color light, expressed as a percentage).
(4) The ability of a glossy mineral or mineral aggregate surface to reflect visible light.
(5) The ability of a solid mineral or mineral product to resist external mechanical action such as scoring, pressing or grinding.
(6) Density The mass per unit volume of ore or mineral product.
(7) Adsorbed water contained in moisture ore or mineral products.
(8) Heat-resistant non-metallic minerals are also resistant to heat when they are heated, and are usually expressed by heat-resistant temperature (°C).
(9) The performance of acid-resistant non-metallic minerals against corrosion of various acid substances is usually expressed by the amount of acid etching (%).
(10) The performance of alkali-resistant non-metallic minerals against corrosion by various alkali substances is usually expressed by the amount of alkali etching (%).
(11) Insulating non-metallic minerals have properties of non-conductivity or non-thermal conductivity.
