Removing Iron by Magnetic Separation from a Potash Feldspar Ore刘艳杰1,彭会清1,HU Mingzhen21. School of Recourses and Environment Engineering, Wuhan University of Technology2. China Tin Group Co., Ltd摘 要:A new permanent magnetic separator was introduced to treat the ores with the characteristics of weak magnetic iron minerals and in a fine size range. The new......
,Northeastern University摘 要:This study focuses on the reduction of phosphorus from high-phosphorus-content oolitic iron ore via coal-based reduction... when the C/O ratio exceeded 2.0. According to scanning electron microscopy analysis, the iron ore was transformed from an integral structure to metal and slag fractions during the reduction process......
Accelerating leaching of copper ore with surfactant and the analysis of reaction kineticsChun-ming Ai1,2,Ping-ping Sun1,Ai-xiang Wu2,Xun Chen2,Chao Liu31. College of Safety Science and Engineering... was analyzed. The results show that the action modes of the surfactant were divided into four aspects: changing the wettability of the ore, reducing the viscosity of the leaching solution, adsorbing onto......
