beneficiationTreatment of raw material (such as pulverized ore) to improve physical or chemical properties in preparation for further processing. Beneficiation techniques include washing, sizing of particulates, and concentration (which involves the separation of valuable minerals from the other raw materials received from a grinding mill). In large-scale operations, various distinguishing properties of the minerals to be separated (e.g., magnetism, wettability, density) are exploited to concentrate the desirable components. Beneficiation also is used in the ceramics and clay industries. See also flotation; mining; mineral processing. beneficiation [‚ben·ə‚fish·ē′ā·shən] (metallurgy) Improving the chemical or physical properties of an ore so that metal can be recovered at a profit. Also known as mineral dressing. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

| Process for the microwave beneficiation of discolored kaolin clay materials Since the available product "spent sand" is contaminated to various degrees and because such contamination may vary significantly from foundry to foundry, the asphalt industry is in no position to judge what degree of beneficiation would be needed to meet its quality criteria. Consulting in the fields of corrosion and corrosion control by inhibitors in sour gas systems, grinding balls, microbiological corrosion, corrosion of low-leaded copper-base alloys, hydrogen damage in high-strength and rail steels, galvanic corrosion of household plumbing solders and contamination of drinking water, surface quantification of corrosion products, electrochemical sensors for hydrogen in steels, reverse osmosis and water pollution and beneficiation of ores. |
