Embodiment 1

[0024] A mining method for placer, specifically comprising the following steps:

[0025] (1) Conduct detailed survey, measurement, calculation and statistics on the mining area first, and install and debug excavators, crushers, vibration screening devices, sand washing machines and other equipment;

[0026] (2) Determine the main parameters of deep hole blasting according to the geological data and the actual drilling geological conditions on site, and blast the excavation face. Among them, the depth of the blast hole for deep hole blasting is 5m, the amount of explosives is 3kg, and the plugging is 0.5m;

[0027] (3) Use an excavator to send the blasted placer into the crusher for crushing. After the crushed placer is vibrated and screened, it is sent to a sand washing machine filled with ore washing liquid for washing of the placer. The sand washing machine The internal ultrasonic vibration frequency is 20kHz, and the cleaned sewage flows into the sewage treatment equipment ...

Abstract

The present invention relates to the technical field of placer mining, in particular to a method for mining placer, comprising the following steps: 1) surveying and measuring the mining area, and installing and debugging equipment such as excavators and crushers; 2) Blasting and mining working face; 3) Vibration screening after crushing the placer, and cleaning of the placer and sewage treatment; among them, the ore washing liquid is mainly extracted from lemon extract, saponin extract, sapindus extract, and tea meal Liquid, absolute ethanol, oxalic acid and fatty alcohol polyoxyethylene ether; sewage treatment agent is mainly made of activated carbon, polyaluminum ferric sulfate chloride, polyacrylamide, Bacillus sporogenes, Aspergillus oryzae and Bacillus licheniformis; 4) Grinding, calcining, cooling and storage. The method is simple to operate, effectively removes rust, yellow spots, and stains, reduces impurities in the placer, improves the whiteness and purity of the placer, and restores the original color, texture, and visual effect of the placer, thereby improving the quality and qualified utilization of the placer Rate.

Description

technical field [0001] The invention relates to the technical field of placer mining, in particular to a method for mining placer. Background technique [0002] Placer is a mineral deposit formed by the accumulation of stable and mechanical debris separated from rock or rock bed during surface weathering, erosion and transportation. Minerals related to placer include gold, tin, diamond, rutile, etc., which play an important role in national defense, metallurgy, and cutting-edge science. Therefore, many countries pay more attention to the exploration and development of placer deposits. At present, there are many impurities in the newly mined placer, and the sewage from washing the placer is directly discharged, which will pollute the environment. Therefore, how to mine the placer, how to remove the impurities in the placer and treat the sewage have become the focus of people's attention. Contents of the invention [0003] The purpose of the present invention is to: aim a...
