某微粒铅锌精矿中钾赋存状态研究

Study on the State of Potassium Occurrence in A Particle Lead-zinc Concentrate

微粒矿物的鉴定受到光学显微镜本身放大倍数的限制很难准确鉴定,利用MLA和X射线衍射分析、能谱分析等与显微镜下观测相结合的方法,弥补了显微镜的不足。通过研究查明了某铅锌精矿中钾的赋存状态,钾元素赋存在钾长石中,钾长石的解离度在35%～40%之间。这一研究成果为有效降低钾元素提供了科学依据。

The particulate mineral identification is limited by optical microscope magnification itself is difficult to accurately identify, this paper use MLA and X ray diffraction analysis, energy spectrum analysis and microscope observation, the method of combining to make up for the deficiency of the microscope. The occurrence of potassium in a lead-zinc concentrate was ascertained through study. Potassium is mainly K-feldspar, and the dissolution degree of K-feldspar is between 35% and 40%. This study provides a scientific basis for the effective reduction of potassium.
