肯尼亚萤石有限公司是肯尼亚唯一的萤石生产厂家,在前年集中力量降低酸性矿石中的磷杂质。过去,精矿中P_2O_5的含量在0.5%左右,这些杂质给该公司的产品在销路上带来了很大的困难。在1985年8月这家公司委托北威尔士兰达诺地区的罗伯逊国际研究有限公司,研究这个难题,寻求降低P_2O_5的途径。兰达诺的实验室研究表明,在浮选回路中添加多种药剂抑制磷灰 Fluorite Co., Ltd. of Kenya is the only fluorite manufacturer in Kenya, concentrating its efforts on reducing phosphorus impurities in acid ores two years ago. In the past, the concentrate P_2O_5 content of about 0.5%, these impurities to the company’s products in the market has brought great difficulties. In August 1985, the company commissioned Robertsons International Research Limited in North Rand, North Wales, to study the problem and look for ways to reduce P_2O_5. Labuan’s laboratory studies have shown that adding a variety of agents to the flotation circuit inhibits phosphorous
