Abstract

The invention discloses a mineral recovery method for a carnallite salt pan. The method comprises the following steps: draining a carnallite salt pan until part of the surface of carnallite ores is exposed; gathering carnallite ores by an excavator, forming a fishbone-shaped stacked ore belt in the carnallite salt pan, wherein the stacked ore belt comprises a main road and a plurality of branch roads communicated with the main road, and the widths of the main road and the branch roads are set according to the requirements for moving a transportation tool; excavating carnallite minerals on thetwo sides of the branch roads from far to near with respect to the main road as a reference, making a transport tool for transporting carnallite ores move along the branch roads and the main road; excavating carnallite ores on the two sides of the main road from far to near with respective to the entrance of the main road as the reference, and making a transportation tool for transporting the carnallite ores move along the main road. Carnallite ores are collected through the excavator to form fishbone-shaped stacked ore belts to cover the salt pan bottom plate, a main road and branch roads fora transportation tool to move are provided, the salt pan bottom plate cannot be damaged, and the harvesting is rapid and efficient.

Description

technical field [0001] The invention relates to the technical field of mining production, in particular to a mineral recovery method for a carnallite salt field. Background technique [0002] Qinghai Chaerhan Salt Lake is a large-scale potash fertilizer production base in China, with an annual potash fertilizer production scale of about 5 million tons. The main process of potassium fertilizer production is to transport the intercrystalline brine to the artificially built large-area salt ponds (commonly known as salt pans). The salt pans use solar energy to naturally evaporate and dry to form carnallite ore, and then mine carnallite ore and send it to the processing workshop Production of potash fertilizers. [0003] There are generally two methods of mining carnallite ore in Yantian, one is commonly known as "dry mining", which relies on excavators and cars to transport carnallite ore in salt fields to the processing workshop, and the other is commonly known as "water minin...
