陕西金家河磷矿是 一座年处理矿石20万吨 的采选联合企业。该矿 矿床属泥盆纪浅海沉积磷块岩矿床。磷矿物主要为胶磷矿,次为磷灰石;脉石矿物主要为碳酸盐,次为石英、绢云母、炭质等。化工矿山设计研究院、长沙矿冶研究所和陕西省地质局实验室,曾先后三次作过中小试验,取得较好指标。 选厂从1979年开始建设,1983年7月全部竣工。由省化肥公司等五个单位组成试车指挥部,经过充分的准备,于1983年10月16日至12月6日共五十一天投料试车,获得成功。工艺指标接近和部分达到设计要求,为生产打下了基础。
Shaanxi Jinjiahe phosphate rock is an annual processing ore 200,000 tons of mining and dressing joint ventures. The ore deposit belongs to the Devonian shallow sea sedimentary phosphorite deposit. Phosphorus minerals are mainly colloidal phosphate, followed by apatite; gangue minerals are mainly carbonate, followed by quartz, sericite, carbonaceous and so on. Chemical Mining Design and Research Institute, Changsha Institute of Mining and Metallurgy and Shaanxi Provincial Bureau of Geology laboratory, has made three small and medium trials, achieved better indicators. Construction plant started construction in 1979, completed in July 1983. By the provincial fertilizer company composed of five units such as test headquarters, after sufficient preparation, in October 16, 1983 to December 6, a total of 51 days feeding test, a success. Process indicators close to and part of the design requirements laid a foundation for production.
