在地质知识(1955年第7期)上看到了“矿石体重的测定”一文后,结合我们在铁矿勘探工作中的一些体会,对这个测定工作的操作步骤、注意事项以及在工作中的经验教训,作一简要介绍。有错误或不够的地方,请同志们指出,互相研究和改进。一、三种实验室体重测定的方法在矿产普查及初步勘探阶段中,一般只要求得出C级储量,因此矿石体重的测定可采用一些比较简单的实验室方法。普通常用“封腊排水法”测体重,采取像肥皂盒大小的矿石块,在天秤上称其重量,然后封腊排水,求其体积。体积(腊膜体积不计)除重量得出体重。
After I saw the article “Determination of Ore Weight” in Geological Knowledge (No. 7, 1955), combined with our experience in iron ore exploration, the operational procedures, precautions and experience in the work of this determination Lesson, make a brief introduction. Where there is something wrong or not, please comrades point out that they should study and improve each other. First, the method of three laboratory weight determination In mineral prospecting and preliminary exploration stage, generally only requires the C-level reserves, so ore weight determination can be used some relatively simple laboratory methods. Commonly used “seal wax drainage method” to measure the weight, take the size of a soap box like ore blocks, weigh the scales on the weight, and then sealed wax drain, find its volume. Volume (wax film volume excluding) in addition to weight gain weight.
