Germanium mud pretreatment method

Abstract

The invention discloses a germanium mud pretreatment method which comprises the following steps: firstly, filtering to remove glue, oil, sand and other organic matters or inorganic matters with largervolume in equipment cooling liquid and cutting liquid containing germanium mud to obtain germanium mud mixed liquid with fewer impurities, , then carrying out multi-stage sedimentation through a sedimentation tank, uniformly recovering the germanium mud in the sedimentation tank; performing residue-liquid separation on germanium mud mixed liquid collected in the sedimentation tank through a filter press to obtain germanium mud residues with less water content, performing wet grinding on the water-containing germanium mud residues obtained through filter pressing in a grinding machine to obtain germanium mud with finer particle size to reduce flying loss in the process, finally drying and dehydrating the grounded germanium mud to obtain high-grade germanium mud containing trace water and having finer granularity to serve as a raw material for chlorination distillation for extracting germanium tetrachloride. The method solves the problems that in the initial germanium mud pretreatment process of an existing germanium mud treatment technology, germanium flying loss is too serious, harm to the human body is obvious, and the extraction requirement cannot be met.

Description

technical field [0001] The invention relates to the technical field of germanium blank parts processing, in particular to a germanium mud pretreatment method. Background technique [0002] In the process of processing germanium blank parts, due to various reasons such as processing technology, equipment, technology, etc., the loss in the process of processing germanium is relatively large, and it is mainly produced in the form of germanium sludge. Germanium mud will contain other inorganic or organic substances to varying degrees. At present, the impurities contained in germanium mud mainly include adhesive glue, oil, water, sand and other organic substances in cutting fluid. Due to the current germanium mud recovery process and equipment are not available. Perfection has led to difficulty in recycling germanium mud, increased labor intensity, and failure to obtain timely and effective recycling, resulting in high production costs, waste and loss of resources.
