Better Results for your mine Water Treatment

Comply with environmental laws and lower your costs by advancing your mine water treatment processes

According to the international council of mining and metals: mining companies viewed water like any other production input. But this has changed in recent years. Water scarcity is a growing challenge in the mining environment. Mining requires water at almost every stage of the process and the bulk of the assets of major mining companies are in water-stressed regions mostly in the southern hemisphere. For many mining companies water is being considered as a strategic resources rather than just only rocks.

Water plays a crucial role for mining operations. Not only the people working in mines rely on it but also many of the mining processes consume an average of 10 megaliters of water a day. This can be a problem as a lot of mines are situated in remote areas without a sufficient access to water. And the preparation of the water used in processes like leaching or flotation consumes energy and chemicals. Finally, mines must discharge the used water back into the environment without harming it in accordance to local standards and in conjunction to the mines water use license.

More and more mines rely on water extraction processes like reverse osmosis to ensure their water supply. But such processes have to be closely monitored to ensure the results. Same goes for the preparation of the industrial water. Only with a tight control of parameters like pH and dissolved oxygen, the usage of energy and chemicals can be optimized. Same goes for the treatment of the water after it has been used to make sure, environmental regulations are fulfilled.

Reverse osmosis is one of the most common raw water preparation techniques. It relies on filtering the water through special membranes. The challenge is, to have as long as possible filtration cycles without harming the membranes which are prone to blockages and processes like fouling and scaling. Therefore the most important parameters on the inlet besides flow is the differential pressure measurement over the filter.

Mine Water preparation is one of the most important process for mining water. A neutral pH value will ensure the efficiency of the settling and the turbidity  measurement can determine the level of the suspended solids. Digital Memosens sensors are highly accurate and can be easily be calibrated without disturbing the process thanks to a removable head where data is stored. You can connect up to eight Memosens sensors to a Liquiline transmitter CM44x to make water quality control a breeze as well as reducing the cost per measuring points.
