Thanks to the high conditions of reliability and versatility, AODD pumps can be used in numerous application sectors without the need for costly installation operations or sizing calculations.
One of the strengths of AODD pumps is the reduced need for maintenance, compared to other technologies, which minimizes downtime and production interruptions. For this reason, double diaphragm pumps represent a valid solution for extractive production processes, increasing their efficiency and safety.
Before discovering how to use diaphragm pumps in the mining sector, we define what is meant by the mining sector. The mining and quarrying sector includes all processes aimed at extracting valuable resources from the earth, specifically non-renewable resources: fossil fuels, minerals, water and precious metals. There are four methods of mining that differ mainly in the type and location of the deposit to be extracted. Each of these methods involves different levels of safety and environmental impact. In particular:
Double diaphragm pumps, while being used in all the types of extraction described above, are used more frequently within underground extraction processes. Let’s now see in what modality
Air-operating double diaphragm pumps are widely used for mine dewatering operations. These operations consist of pumping mine water from lower basins and transferring it away from the working areas, usually to a central pond. This process keeps the work area free of deep water, increasing the safety conditions of the miners and the surrounding production environment. However, it is necessary to consider three important aspects related to the use of the correct pump technology:
AODD pumps are used in the type of “placer extraction” where the rock and minerals are crushed and sieved and then rinsed by a filtering chemical that captures and extracts the mineral from the piles of crushed materials. In this case the task of the aodd pump is to dispense and transfer the leaching chemical. The aspects to be taken into consideration are the following:
The AODD pumps are used as part of the water treatment operations removed from the underground mine or from the surface extraction area. Water, usually placed in a sedimentation pond, can contain contaminants and in many cases, especially in coal mining, can be very acidic. To protect the environment, water must be neutralized and treated before being released into the environment. AODD pumps are used to dispense neutralizing chemicals, flocculants and other process chemicals. They are also used to transfer water to tankers if water removal and treatment involves moving to a different location. The factors to consider for the use of AODD pumps in this activity are as follows:
DEBEM double diaphragm pumps can be used in a wide range of applications and extractions: from dewatering activities in aquifers to transferring drilling muds, washing and separating minerals to water and sludge treatment.
