新浦磷矿属沉积变质磷灰岩矿床,矿石硬度中等,原矿品位18～27％P_2O_5,磨细后可作为商品矿粉出售。为了降低磨矿能耗,我们对有工业价值的一些助磨剂进行了试验和选择。 目前,国外对助磨剂的研究尚处于试验阶段,仅有少数工业实例,我国的研究工作基本上仍处于实验室试验阶段。针对新浦磷矿的矿石特点和现实条件,我们对以下16种助磨剂进行了试验筛选:乙二醇、异戊醇、丙酮、硫酸锌、氢氧化钠、碳酸钠、氯化钠、硫化钠、氟化钠、水玻璃,六偏磷酸钠、炭黑、油酸、油酸钠、硝基腐植酸
Xinpu Phosphate deposit is a sedimentary metamorphic apatite deposit with medium hardness and ore ore grade of 18-27% P2O5, which can be sold as commercial ore powder after being ground down. In order to reduce grinding energy consumption, we tested and selected some grinding aids with industrial value. At present, foreign research on grinding aids is still in the experimental stage, only a few industrial examples, our research work is still basically in the laboratory test stage. According to the characteristics and actual conditions of Xinpu phosphorite ore, we tested the following 16 kinds of grinding aids: ethylene glycol, isoamyl alcohol, acetone, zinc sulfate, sodium hydroxide, sodium carbonate, sodium chloride, sodium sulfide , Sodium fluoride, water glass, sodium hexametaphosphate, carbon black, oleic acid, sodium oleate, nitro humic acid
