Method of building up

According to the level of equipment and production capacity of mines, the commonly used methods of pile-up methods are:

1. Method partial stack piled    That is, a belt conveyor is used to build a series of small ore piles higher than the height of the designed ore pile, and the top of the pile is flattened by a bulldozer. This method of pile-up is prone to segregation, that is, when the belt conveyor is unloading, the coarse particles roll down on the side and the fine particles are in the pile, forming their respective grain size areas, causing the leaching solution to flow uniformly through the entire pile. Reduce the leaching effect of gold . In practice, measures should be taken to avoid it.

2. Layered pile method    That is to say, by means of the height difference of the terrain or using a waste rock to build a slope leading to the bottom pad, a certain height difference is caused, and the ore is pushed forward and layered from the bottom to the top. When building the pile, it should be noted that only a narrow road is taken after the dump truck is piled up, and the unloaded ore is pushed to the surrounding with a bulldozer, and attention is paid to loosen the compacted part in time. In this way, the layers are gradually advanced and stepped up until the design requirements are reached. This is the more common method of building. As shown below :

The above two types of pile-up methods are relatively low in equipment and equipment, require simple technical operation and low investment, and are used in some domestic dumping fields.
