某地輝銻矿的选矿工作,直到目前为止都是采用手选法,这种选矿法是远远不能滿足我国工业需要的。为了配合我国重工业的发展,对該矿石进行研究,实为当前迫切的任务。本文是概括某地輝銻矿浮选方面的某些因素,并嘗試介紹有关該矿石的一些研究方法和結果。 礦石的物理性質与化學成份 (一)主要矿石矿物所处理的矿样中主要矿石矿物为輝銻矿,其結构有下列几种: 自形晶結構——輝銻矿多呈稜柱状、放射状等完整的晶形,除基底附生于石英休或硅化灰岩之外,不与其他矿物共生。在块狀辉銻矿中,一般亦呈粗大的自形晶,錯縱穿插成緻密狀与石英連生在一起的輝銻矿多呈半自形或其他形結構。
A stibnite ore beneficiation work, until now are by hand-election method, this mineral processing method is far from meeting the needs of China’s industry. In order to cope with the development of China’s heavy industry, research on this ore is actually an urgent task at present. This article summarizes some of the factors involved in the flotation of stibnite in a certain area and attempts to introduce some research methods and results on this ore. Ore physical properties and chemical composition (a) the main ore minerals processed ore samples in the main ore minerals stibnite, its structure has the following: self crystal structure - stibnite mostly prismatic, radial, etc. Complete crystal form, in addition to the base attached to the quartz off or silicified limestone, not with other minerals symbiosis. In the massive stibnite, usually also showed a large self-shaped crystal, wrongly inserted into the dense and quartz together with the stibnite mostly semi-self-shaped or other shaped structure.
