一种简易的镍黄铁矿单矿物提取方法
摘要：
本发明公开一种简易的镍黄铁矿单矿物提取方法，该方法以铜镍硫化矿为原料，通过永磁铁向铜镍硫化矿施加磁场强度逐渐增大的磁场，从而对铜镍硫化矿进行逐级磁选，其特点在于，收集磁场强度为250 mT时被吸起的矿物，所得矿物中镍黄铁矿纯度达90%以上。相比于人工合成矿物，本发明方法避免了苛刻的反应条件与漫长的反应时间，并且所得镍黄铁矿单矿物的数量大大增加；相比于传统镍黄铁矿单矿物的分选，本发明方法易于操作，并且在分离过程中保持了镍黄铁矿表面物理化学性质。
摘要（英）：

The invention discloses a simple method for extracting pentlandite monominerals. The method is characterized in that copper-nickel sulphide ore is used as a raw material, and a magnetic field of which the strength gradually increases is applied to the copper-nickel sulphide ore through a permanent magnet, so as to achieve stage-by-stage magnetic separation of the copper-nickel sulphide ore. The method is characterized in that minerals which are absorbed when the strength of the magnetic field reaches 250mT are collected; the purity of pentlandite in the obtained minerals is more than 90%. Compared with an artificial mineral synthesizing method, the simple method for extracting the pentlandite monominerals has the advantages that severe reaction conditions and long reaction time are avoided, and moreover, the quantity of the obtained pentlandite monominerals are greatly increased; compared with a traditional separation method of the pentlandite monominerals, the simple method for extracting the pentlandite monominerals is easy in operation and remains the physicochemical properties of the pentlandite surfaces during the separation process.
