为了产出高品位铁精矿,曾经进行过用预先进行酸、碱处理的办法来强化磁铁矿精矿的浮选和磁选的研究。这些研究是用各种矿物——假象赤铁矿、磁铁矿、石英、镁铁闪石,以及北方和南方采选公司的磁铁矿精矿进行的。在试验之前,先将矿物磨碎至粒度为-0.15+0.01毫米。而后用碱或者酸对其进行处 In order to produce high-grade iron concentrates, studies have been conducted to enhance the flotation and magnetic separation of magnetite concentrates by pre-treating acid and alkali. These studies were conducted with a variety of minerals - faux hematite, magnetite, quartz, mafic and magnetite concentrates from northern and southern mining companies. Prior to testing, the minerals were first ground to a particle size of -0.15 +0.01 mm. It is then treated with an alkali or acid
