Embodiment Construction

[0022] Such as figure 1 Shown, the present invention is a kind of method that fully utilizes gold tailings, mainly comprises the following steps:

[0023] (1) The tailings of the multi-element workshop enter the cyclone, and the tailings with large and small specific gravity are separated, and the separated materials with small specific gravity after being classified by the cyclone enter the sand washing machine, and after sand washing The screen of the sand washing machine is divided into an underflow part and an overflow part after being screened, and the underflow part of the sand washing machine is the machine-made sand;

[0024] (2) As in step (1), the overflow part screened by the sand washing machine enters the classifier for further classification, and the part with a smaller specific gravity overflows out and enters the next process flow. After screening by the classifier The underflow part becomes machine-made sand.

[0025] The overflow part of the classifier in t...

Abstract

The invention belongs to the field of gold tailing treatment, and particularly relates to a method for fully utilizing gold tailings. The method mainly comprises the following steps that multi-elementtailings are subjected to swirler grading, are further screened through a sand washer, are further graded by a grader, and are screened after being dried to obtain fine sand with different levels; meanwhile, an overflow part with smaller specific gravity graded by the grader is dehydrated and precipitated through a high-efficiency thickener, then layer-by-layer screening is carried out through amulti-stage desliming hopper, finally dehydrating is carried out on the most fine overflow part by using a dewatering sieve to obtain silicon micropowder which is excellent in performance and is widely applied; and a bottom flow which is precipitated by the high-efficiency thickener can be stored in an air-inflation type slurry storage tank, and is used for producing an aerated brick. According tothe method, the multi-element tailing treatment method is more refined, the gold tailings can be thoroughly utilized, no harmful gas is emitted to the environment, the method can be applied to different fields and occasions, maximum utilization of the tailings can be achieved, and the method is the most environment-friendly and most economical tailing treatment method.

Description

technical field [0001] The invention belongs to the field of gold tailings treatment methods, in particular to a method for fully utilizing gold tailings. Background technique [0002] The accumulation of gold tailings increases year by year, which brings many problems such as resources, environment, safety and land. At present, through the analysis of the characteristics of gold tailings, the industry has studied the treatment and comprehensive utilization methods of gold tailings, which can be used to extract gold from tailings again, or to make sand for construction, but there are still insufficient tailings utilization. Thorough disadvantages, or the classification of isolates is not meticulous, resulting in waste of resources. Contents of the invention [0003] The invention provides a method for fully utilizing the gold tailings to improve the existing problems of incomplete utilization of the tailings or waste of resources caused by incomplete classification.
