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%.
