What is mine upgrading? What are the main enhancements?

Mine upgrading is actually the transportation work in the wellbore and an important part of the whole mine transportation system. Mine lifting equipment includes hoists, lifting containers, lifting wire ropes, derricks, sky wheels and handling equipment. Since the mine lifting work is to make the lifting container reciprocate at a high speed in the wellbore, the lifting machine is required to operate accurately, safely and reliably.
1) Lifting machine

At present, China metal and nonmetal underground mines used in mainly single hoist rope Winding Mine machine (there are monocular, binocular two types) and multi - rope friction mine hoist machines.

2) Lifting container

(1) cage

The cage is used for lifting personnel, lifting and lowering materials in the shaft. Depending on the number of layers, there are single-layer cages, double-layer cages and multi-layer cages.

(2) Fighting

The bucket can only raise ore and waste rock. According to different unloading modes, the shaft buckets are divided into three types: bottom unloading type, side unloading type and turning type; inclined shaft buckets have flip type and rear wall unloading type.

Gold Concentrator

The STL water-jacketed gold concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.

The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
