preparation example Construction

[0039] The present invention realizes the working principle and working process of the preparation device for the preparation method of the fermented mixture: first, the soil layer of the fermentation site is compacted and leveled, and then the fermentation bag 1 is positioned on the site according to the size of the fermentation bag. The tables 10 are installed together, and then insert the lower rod into the positioning point to fix the insertion table 10; then place the fermentation bag 1 on the ground, and pass the upper rod of the vertical support rod 2 through the elastic sleeve 5, which can expand the elastic sleeve. 5, in order to pass through the card slot 6; then install the elastic sleeve clamping rod 8, so that the elastic sleeve 5 is stuck, preventing the elastic sleeve 5 and the fermentation bag 1 from slipping off, and at the same time, the fermentation bag 1 is initially held up; then the fermentation bag 1 Stand up, and at the same time insert the lower end of ...

Abstract

The invention discloses a method for copper tailing soiling in high-cold and high-altitude area. The method comprises the following steps of sieving copper tailings, and paving oversize materials on the ground; spreading a fermentation mixture, and conducting ploughing; conducting earthing, and applying a water-retaining agent while earthing is conducted; spreading plant ash; planting green manureplants; and spreading sawdust on planting land. According to the method, the adopted raw materials are wide in source and large in quantity, local materials are convenient to use, the raw materials are used on site, cost is low, and meanwhile environmental pollution is reduced; the fermentation mixture and the plant ash can effectively promote formation of a soil aggregate structure, the loose and ventilated state of the soil is kept, and the water retention, heat preservation, ventilation and fertilizer retention capacities are improved; and the sawdust is beneficial to heat preservation andwater retention, and the planted green manure crops can also increase the contents of organic matters, nitrogen, phosphorus and potassium in the soil, and the soil is loosened. The method is simple to operate and has important practical significance for efficient utilization of the copper tailings.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and particularly relates to a method for soiling copper tailings in high-cold and high-altitude areas. Background technique [0002] Copper tailings refer to the solid waste discharged from mines that mainly exploit copper ore resources. For every ton of mined copper produced, 400 tons of waste rock and tailings are produced. The massive discharge of copper tailings not only occupies vast land resources, but also the environmental pollution caused by copper tailings seriously threatens the living environment and normal life of human beings, and even destroys the balance of the ecosystem. At present, the main utilization methods of copper tailings in my country are the extraction of valuable components from tailings, mining and filling, and the preparation of building materials. However, there are many problems in the utilization of copper tailings in my country, such as low com...
