Heaping method using dumping plough for mine dump leaching field

Abstract

The invention discloses a heaping method using a dumping plough for a mine dump leaching field. The heaping method comprises the following steps of S1, firstly, a double-side heaping step is executedby using the dumping plough, specifically, heaping is carried out continuously on two sides of a first moving sealing-tape machine by using the dumping plough to form a first dump leaching unit, wherein the first heap leaching unit comprises two parallel material piles formed by stacking materials, and a safe distance is reserved between the two parallel material piles so as to form a valley bottom part clamped between the two parallel material piles; S2, a moving step is executed, specifically, the dumping plough and the first moving sealing-tape machine are moved out of the two ends of the valley bottom part correspondingly, and then the dumping plough and the first moving sealing-tape machine are moved to a site where another second heap leaching unit is formed; and S3, the double-sideheaping step S1 and the moving step S2 are repeatedly executed. According to the method, heaping is conducted through the dumping plough with a crawler belt, double-side heaping can be moved at a time, and the moving frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a heap building method using a soil dumper for a mine heap leaching field. Background technique [0002] Heap leaching is a metal smelting process that sprays a metal ore pile with a solution to infiltrate and dissolve useful components, and then concentrates and recovers the rich solution. It is mostly used for large-scale, low-grade copper ore, uranium ore, etc. Among them, the process of evenly spreading the crushed metal ore in the heap leaching field is called heaping. According to the size of the mine and the distance between the heap leaching site and the crushing station, commonly used heaping equipment includes loaders, bulldozers, dump trucks, and distributors. [0003] Stacking by loaders and bulldozers is only suitable for small-scale production. Large-tonnage mining dump trucks can be used in large-scale mines, but the compaction of tires on ore piles will affec...

AI Technical Summary

Problems solved by technology

Large-tonnage mining dump trucks can be used in large-scale mines, but the compaction effect of tires on ore piles will affect the leaching rate, and the economics of truck piles will decrease significantly with the increase of transportation distance

The special bridge-type distributing machine is a multi-track walking truss steel structure with belt conveyors and unloading vehicles on it. It is especially suitable for large-area and regular-shaped rectangular heap leaching units. The disadvantages are that it is expensive and expensive. Unable to build stacks on irregular terrain and requires high levels of operators
