PROXA treats effluent mine water to potable standards for Glencore.
Izimbiwa Coal Middelburg Complex needed the treatment of excess opencast mine water to ensure continued access to resources and to protect the environment. The composition of the feed is typical of mine affected water quality associated with coal mining, containing high levels of metals and sulphates.
Given that the duration of treatment and the future volumes were uncertain, we installed a modular plant, allowing for future expansion and ease of rehabilitation.
HOW PROXA ADDED VALUE
Apart from developing a modular SLD solution, we are responsible for the operations and maintenance supervision of the water treatment plant, including technical support and optimisation of the lifecycle costs associated with the operations of the plant.

In dealing with variable feed streams such as contaminated mine water, process robustness and operational flexibility is of critical importance in continuously meeting environmental discharge requirements. PROXA is a leader in the field of process innovation. Through our in-house process development laboratory, PROLAB®, and the support of PROSERV® – which optimises life cycle costs for chemicals, consumables and spares – we’re able to assist with the rapidly changing requirements of mining clients.
PROXA has a proven track record in delivering and operating systems capable of treating variable effluent mine water, working with all stakeholders to ensure protection of the environment, and supplying potable water to surrounding villages.
