在矿山设计中为确定选矿工艺流程和各项技术经济指标进行的选矿试验,是以选矿试样为基础来实现的,而选矿试样的使用价值,则取决于所采试样是否具有代表性.以往依据采样设计所采试样,虽然大部份能够被试验研究部门所利用,然而,在金和主要伴生有益组分的品位,矿石类型,金的粒度和嵌布特征,矿石含泥量等方面,往往满足不了采样设计预期的代表性要求,致使有的矿山投产后,选矿回收率达不到设计要求.也有的矿山确定的选矿工艺流程不够合理,
The beneficiation tests for determining the beneficiation process and various technical and economic indicators in the design of mines are based on the beneficiation samples and the value of the beneficiation samples depends on whether the samples to be taken are representative In the past, samples taken from a sampling design, although most of them could be used by the experimental research group, however, were different in the grade of gold and major associated benefit components, the type of ore, the size and inlaid characteristics of gold, Often can not meet the expected requirements of sampling design requirements, resulting in some mines put into operation, dressing recovery rate of less than the design requirements.Many mines to determine the beneficiation process is not reasonable,
