Mine drainage refers to surface water or groundwater discharged from mining or abandoned mine areas. The water quality of mine drainage may be as good as natural water, or it may be contaminated by waste materials. The polluted mine drainage is extremely acidic and contains high concentrations of toxic heavy metals. In general, the more acidic the water, the more harmful it is to living organisms.

Mine drainage results from a chemical reaction between water and mineral rocks containing sulfur, mine drainage is rich in sulfuric acid and dissolved iron. When iron settles in river water, it forms red, orange or yellow deposits on the river bottom. Acid runoff further dissolves heavy metals such as copper, lead, and mercury into groundwater or surface water. Normally, the chemical reactions caused by mine drainage proceed slowly, but they can be accelerated by certain bacteria. The amount of water inflow in mines changes seasonally, peaking in the rainy season (or snow melting period), and the maximum inflow can be 1.5 to 3 times or more of the normal inflow. In the case that the water-filled ore deposit has not been completely drained, it is necessary to rely on drainage to create a good working environment for the mining work and the health and safety of workers, so as to ensure the smooth progress of production. Both open-pit and underground mining must have good drainage systems and equipment.

According to this special working condition, OCEAN Pump has designed a one-button start-stop dewatering pump system, and is equipped with a safe and reliable land-use engine. The water pump is equipped with wear-resistant and corrosion-resistant parts according to different materials, and the form of vacuum perfusion water diversion is selected. At the same time, the floating tank containing the oil tank can be selected at the bottom of the pump unit.

The comprehensive utilization of tailings mainly includes two aspects: one is re-selection of tailings as secondary resources to recover useful minerals; the other is direct utilization of tailings for filling mining, road construction, and preparation of organic fertilizers and building materials (cement, bricks, aerated concrete, refractories, glass, ceramsite, glass-ceramics, etc.). The tailings can also be used in combination, that is, the valuable components in the tailings are comprehensively recovered first, and then the tailings are directly used to realize the comprehensive utilization of the tailings.

The 30-year research on the extraction of tailings pump by the ocean pump industry, combined with the tailings recovery device can effectively reduce the loss of tailings, and control it below 3% (calculated by volume), effectively reducing the content of active ingredients in the tail water, and solving the problem of tailings The pollution of mines to the environment meets the emission standards required by environmental protection.

It is widely used in metallurgy, mining, water conservancy, hydropower, sand and gravel factories, glass factories, coal preparation plants, crude coal recovery and environmental protection projects, and shield machines (mud purification) and other engineering projects.

Ball mills, rod mills, and semi-automatic mills are designed with mill grooves to collect any material that falls from the circuit.

In addition to the original minerals themselves, grinding balls, rod fragments, and other hard materials that may fall from the mill can also be found in these pits.

Then, the mill grooves collect all these solids and require structured maintenance to avoid overfilling and loss of operability.

In these situations,OCEAN Pump electric pump has always been the preferred solution for the mining department, replacing the standard loader method used in mines, greatly reducing its operating costs, operator requirements, and project completion time.

Private marinas, as well as the surrounding waters, have a large amount of sediment and require regular maintenance and dredging. OCEAN Pump has designed compact dredging systems to carry out these maintenance operations.
