Embodiment 1

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

[0025] (1) First conduct detailed survey, measurement, calculation and statistics of the mining area, and install and debug equipment such as excavators, crushers, vibration screening devices, and sand washing machines;

[0026] (2) Determine the main parameters of deep-hole blasting based on the geological data and the actual drilling geological conditions on site, and blast the mining face. Among them, the depth of the blasthole for deep-hole blasting is 5m, the amount of explosive is 3kg, and the blockage is 0.5m;

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

Abstract

The invention relates to the technical field of placer mining and specifically relates to a placer mining method comprising the following steps: 1) carrying out reconnaissance, measurement and other operations on a mining region, and mounting and debugging equipment such as an excavator and a crusher; 2)detonating and excavating a working surface; 3) crushing a placer, then, carrying out vibratoryscreening, placer washing and sewage treatment, wherein an ore washing liquid is mainly prepared from a lemon extracting solution, a saponin extracting solution, a soapberry extracting solution, a tea seed cake extracting solution, absolute ethyl alcohol, oxalic acid and fatty alcohol polyoxyethylene ether, and a sewage treating agent is mainly prepared from activated carbon, polymeric chlorinated iron-aluminum sulfate, polyacrylamide, bacillus laterosporus, aspergillus oryzae and bacillus licheniformis; and 4) carrying out polishing, calcining, cooling and storage. The method is simple in operation and can be used for effectively eliminating rusty spots, yellow spots and dirty marks of the placer, reducing placer impurities, increasing the whiteness and purity of the placer and recovering the original color, texture and visual effect of the placer, so that the quality and qualified utilization ratio of the placer are improved.

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 deposit formed by the accumulation of stable mechanical debris from rocks or buckle L beds in the process of surface weathering, erosion and transportation. The minerals related to placer mines include gold, tin, diamond, rutile, etc. They all occupy important positions in national defense, metallurgy, and cutting-edge science. Therefore, many countries pay more attention to the exploration and development of placer deposits. However, there are many impurities in the newly mined placer, and the direct discharge of sewage from washing the placer will cause environmental pollution. Therefore, how to mine the placer, and how to remove the impurities in the placer and the treatment of sewage have become the focus of more attention. Summary of the invention [0003] The purpose of the present invention is to prov...
