牙买加铝土矿的已探明储量为25亿t,地质品位Al_2O_3 45％～50％,SiO_2 0.5％～2％,Fe_2O_316％～25％,复盖层厚0.2～0.5m,矿体呈“鸡窝状”,总年产量1160万t,氧化铝年产总量306万t。美国EG&G公司对应用中子活化快速分析仪分析铝土矿持积极态度。X萤光分析仪适用于我国铝矿山。牙买加铝土矿配矿主要是控制一水软铝石含量;以租赁方式使用土地,复垦费用计入采矿成本;用雷达探矿,可使一个小矿体从圈定到钻孔求出储量和质量仅需12小时。列表表明各铝企业产能和合资比例;简述三个氧化铝厂的生产技术特点及基本参数。
The proven reserves of bauxite in Jamaica is 2.5 billion t, geological grade of Al 2 O 3 45% ~ 50%, SiO 2 0.5% ~ 2%, Fe 2 O 3 16% ~ 25%, cover thickness 0.2 ~ 0.5m, ore body was “chicken Nest-shaped ”with a total annual output of 11.6 million tons, total annual output of 3.06 million tons of alumina. EG & G Corporation of the United States on the application of neutron activation rapid analyzer analysis of bauxite positive attitude. X fluorescence analyzer for China’s aluminum mines. Jamaica bauxite ore is controlled mainly by controlling the amount of boehmite; land is leased and reclamation costs are included in the cost of mining; prospecting with a radar allows a small ore body to be delineated and drilled for reserves and quality Just 12 hours. The list shows the production capacity of aluminum companies and the proportion of joint ventures; briefs on the three alumina plant production technology features and basic parameters.
