Portable automatic ore dressing and sample screening device and using method thereof

Abstract

The invention discloses a portable automatic ore dressing and sample screening device. The device comprises a box, wherein the box is internally provided with a mains haft I, the top of which is movably connected with the top of the inner wall of the box; the bottom of the main shaft I passes through the bottom of the inner wall of the box to reach the downward side of the box; and a needle is fixedly mounted at the bottom of the main shaft I. the device has the beneficial effects of being simple in structure and convenient to operate, being used without externally arranging a power source, being suitable for remote areas, convenient to carry and simple and convenient in operation process, being capable of rapidly sucking drilled and ground ore powder into a collection barrel in the deviceand carrying out isolated split charging for preventing mixing by utilizing the principle of draught head, and voluntarily dismounting the collection barrel from the device to sample multiple ores atone time.

Description

technical field [0001] The invention relates to the field of isotope analysis and collection of geological samples, in particular to a portable automatic sample screening device for beneficiation and its use method. Background technique [0002] At present, during the sample processing of rare gas isotope analysis of geological samples, pure single minerals such as quartz, mica, feldspar and cassiterite must be screened out. The current general method is to crush minerals to 40-80 mesh, and then manually screen single minerals in binoculars. However, there is no good tool for manual mineral screening, and self-made simple picks (such as blades) are mainly used. Separation of minerals and subpackage of the same minerals. However, the mineral particles are very small, difficult to separate and easy to stick to the pick, and the operation is quite complicated; the process of subpackaging is also manually transferred to the sample bag, the entire operation process is relatively...
