"Amoy" barite in Baiyuyu Village tailings
Through the analysis and research on the Baiyuyu Village tailings, the new process was determined, and the barite in the tailings was efficiently recycled.  The selected sample is tailings after flotation of copper , lead , zinc and sulfur, and the particle size is fine. The barite beneficiation does not require grinding to directly perform flotation. Pre-desulfurization was carried out on the premise that the mine contained some easily floatable sulfides, which had little effect on the recovery rate of barite. Separation of Copper, lead, zinc, barium sulphate content of the sulfur mineral tailings 36.54% for the primary purpose of minerals containing small amount of calcium, magnesium, aluminum salts, some residual sulphide minerals. The gangue minerals are mainly quartz and barite minerals, and most of them are distributed in the order of -0.075 mm. For the selection of barite coarse concentrate is difficult, the researchers selected the appropriate process and pharmaceutical system, and obtained the ideal selection index, which provided the basis for mineral processing technology for the mine investment and construction.  The project adopts the process of “pre-desulfurization-desulfurization tailings flotation (primary rough selection, one sweeping, secondary selection)â€. The grade of barium sulfate obtained by closed circuit test is 95.76%, and the recovery rate is 82.21%. Barite concentrate and can provide 2.5 kg of qualified heavy minerals.  With a processing capacity of 500,000 tons/year, the annual cost of mineral processing is 109.55 million yuan. The reference price of barite concentrate is 800 yuan/ton, the annual output value of barite concentrate is 124.88 million yuan, and the annual economic benefit of the concentrator is 15.33 million yuan. The economic benefit is remarkable and it has good promotion and application value. compression fittings 's ring has double anneal,It is much better for seal.compression fittings,Connex compression fittings,Plumbing compression fittings compression fittings,Connex compression fittings,Plumbing compression fittings Taizhou Runde Company , https://www.nerausmotor.com
