前言本次岩矿工作是配合我所选矿室朝阳湾金矿试验而作。为选矿除砷试验提供有关矿物组成等方面技术资料。鉴定样品的来源,在矿山地质情况一概不清的情况下,仅从选矿试验大样中有选择的采取76块矿石标本,制作34块光片,8块薄片,又从选矿-2毫米样品中磨制不同粒级团矿两个,仅就朝阳湾金矿矿物种类,矿物相对含量,主要矿物浸染粒度,以及金矿物和砷矿物的嵌布状态,与其他矿物之间的共生关系等作了一些粗浅工作,水平所限,不妥之处,敬请指教。
Preface The rock and mine work is in line with my selected Chaoyangwan gold mine test. For mineral processing arsenic test to provide technical information on mineral composition and so on. Identification of the source of the sample, in the case of mine geological conditions is not clear, only from the mineral processing test samples taken to select 76 large ore samples, making 34 light films, 8 thin slices, and dressing from 2 mm samples Only two types of ore bodies with different grain sizes were milled. Only the mineral types, the relative contents of minerals, the size of the major minerals in the Chaoyangwan gold deposit, the embedded state of the gold minerals and arsenic minerals, the symbiosis with other minerals Some superficial work, the level of limitations, inappropriate, please advise.
