在地质勘探、选矿、冶炼等过程中,常常需要对矿石、原料、产品或中间产品进行磁铁矿含量的测定。目前常用的测定方法有化学物相分析、X射线衍射和磁通量法等。笔者对K值法(比磁化系数法)进行了一些研究,通过一些样品的实测,证明其测量精度可以满足科研和生产的要求。一、原理矿样在不均匀磁场中所受磁力的大小由下式决定:F_m=KMHgradH (1)式中F_m——矿样受到的磁力(达因); K——比磁化系数; M——矿样质量(克); HgadH——比磁力(奥斯特~2/厘米); F_m是矿样中各种矿物所受磁力之总和;即
In geological prospecting, mineral processing, smelting and other processes, often need to ore, raw materials, products or intermediate products for the determination of magnetite content. The commonly used determination methods are chemical phase analysis, X-ray diffraction and magnetic flux method. The author of the K value method (than the magnetization coefficient method) for some research, measured by some samples to prove that the measurement accuracy to meet the requirements of scientific research and production. First, the principle of ore samples in the uneven magnetic field by the size of the magnetic force by the following decision: F_m = KMHgradH (1) Where F_m - ore by the magnetic force (dyne); K - specific magnetization coefficient; M- - the mass of the sample (g); HgadH - the magnetic force (Oersted ~ 2 / cm); Fm is the sum of the magnetic forces of the various minerals in the sample;
