莹石精矿,包括块矿和粉矿,按用途可分为冶金熔剂和化工制酸两大类,其质量标准与矿山的产品方案和订价关系密切。本文拟以浙江东风莹石公司浮选莹石粉的质量标准为例,参考国内外现行标准,对出口莹石粉的分级及其经济意义作一初步探讨,希望有关单位考虑制订我国莹石精矿质量标准。浙江东风莹石公司是我国最大的莹石生产矿山,除早已承担冶金级莹石块和化工级莹石粉出口任务外,计划新建第二浮选厂,年处理能力15万吨。对于该矿化工级浮选莹石粉的质
Fluorite concentrate, including lump ore and fines, can be divided into two major categories of flux and chemical acid according to the purpose. The quality standards are closely related to the product plan and pricing of the mine. In this paper, Zhejiang Dongfeng fluorite company flotation fluorite quality standards, for example, reference to domestic and foreign standards, the classification of export fluorite powder and its economic significance to make a preliminary discussion, I hope the relevant units to consider the formulation of the quality of China’s fluorite concentrate standard. Zhejiang Dongfeng Yingshi Company is the largest production base of fluorite in our country. It plans to build a second flotation plant in addition to the task of exporting metallurgical-grade fluorite block and chemical grade fluorite powder with annual processing capacity of 150,000 tons. For the mineral grade flotation fluorite powder quality
