Device and method for rapidly determining ore grade of copper-nickel sulfide ore

The invention belongs to the field of mine exploration and production, and particularly relates to a device and method for rapidly determining the grade of copper-nickel sulfide ore. The grade of 140-200-mesh ore powder is analyzed through the steps of rock drilling liquid collection, centrifugal classification, drying and cake making, grinding and screening, grade determination through a handheld spectrograph analyzer and the like. The centrifugal grading device suitable for the content of the invention is designed according to self requirements. According to the method, the ore grade determination time is greatly shortened, the problem that the error is large when a handheld spectrograph is used for analyzing mineralized non-uniform ore and star-like-sponge meteorite-like ore is solved, and mine production can be effectively guided. 本发明属于矿山勘探及生产领域，具体涉及一种硫化铜镍矿矿石品位快速确定的装置及其方法，根据矿山生产工艺、矿石结构构造特征，本发明以凿岩过程中产生的岩粉为基础，通过凿岩液收集、离心分级、烘干制饼、研磨筛分、手持式光谱仪分析仪品位测定等步骤分析140-200目矿石粉末品位。本发明根据自身需求，设计出适用于发明内容的离心分级装置。本发明极大缩短了矿石品位确定的
