Barium ore coarse selection technology
Barium ore coarse selection Domestic tantalum-niobium ore grade ore is generally low, its mineral crisp, high density. In order to ensure the grinding size and avoid over-grinding, the stage grinding stage selection process is generally adopted. Yichun tantalum and niobium ore dressing plant with a substituted linear vibration sieve bend laterally sieved, field exploration results showed: 14.70% clamp fine sieve can be reduced, the clip can be reduced coarse sieve of 4.3%, screening efficiency can be improved 17.72 %. The successful test of this equipment provides a new way for the field of grinding and screening. Nanping, Fujian Province is a large-scale granitic pegmatite deposit. In 1998, we conducted ore dressing test on the ore, providing design basis for the construction of the plant. Based on the grain-embedded characteristics of strontium and cassiterite minerals, we proposed to adopt stage grinding and stage. Sorting process. A section uses a rod mill and forms a closed circuit with the screen to reduce over-grinding. The second-stage grinding uses a ball mill and forms a closed circuit with the high-frequency vibrating fine screen. In addition to strictly controlling the particle size, it can also increase the processing capacity and improve the grinding efficiency. The mine is rough selected using a single re-election process. The re-election equipment has a GL spiral concentrator, a spiral chute and a shaker. The ore is selected from the original ore containing (TaNb)2O5 0.0499%, Sn 0.0598%. The crude concentrate obtained after rough selection has a yield of 0.248%, containing (TaNb)2O514.94% (including Ta2O5 10.79%), and the recovery rate of raw ore is 74.30% (Ta2O5 recovery rate is 74.96%); containing Sn 15.71%, the recovery rate of raw ore is 65.11%.
Above-mentioned equipment was successfully developed by Changchun Gold Research Institute in 1998. It has possessed three patents and five monopolized technologies. Desorption solution does not contain sodium cyanide, it can reduce the grade of barren carbon down to 100g/t. The key technology of this equipment is that it can ensure the balance of metal quantity, and avoids gold- accumulating and gold- floating from the equipment, ensures the technological index steady and low cost of it. The content about technological advantages has been broadcasted by Xing Huo Science and Technology of CCTV. This technology was appointed as the energy-saving technology of gold production by National Development and Reform Committee in 2006, and was also appointed as standard equipment in the industry by National Development and Reform Committee in 2007, it passed the technique identifying in 2003, and won the second award of science and technology of China National gold Association, the entire technical level is advanced at home. This equipment has won three patent rights of China. The patent numbers of it are separately: 01241537.5 01241538.5 200620029209.1
