Osmoflo says it is Australia ' s largest desalination company. This picture shows a plant it provided to Consolidated Tin Mines’ Mount Garnet mine
partnership between Outotec and Osmoflo is quite unique in that it provides a combination of skill sets, and mining technology with specialist water treatment and recycling,” Ajay Jaggi, Osmoflo’ s General Manager, Sales – Australia, APAC and Africa explains.
“ This particular project also showcases Osmoflo’ s global ability, with engineering, project management and operations coming from Osmoflo in Australia, India and Chile,” Jaggi
continues. The project is forecast to be completed in May of 2017.
PROXA says that“ 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.
At the Acacia mine located in Tanzania, a plant was built as two-process trains to treat water from a tailings storage facility( TSF) and water from open pits for reuse and discharge.
PROXA was able to maximise the throughput of the plant, while optimising and reducing the
operating costs by > 70 %, which was of critical importance to the strained gold mining sector there at the time.
In Zambia, Konkola Copper Mines needed to treat a raw water supply from the Kafue River to meet four different grades of water for use at the smelter. PROXA’ s responsibility included the pumping, control and supply of the raw water at a rate of 1,500,000 litres / h. The plant was commissioned to produce: process water, cooling tower feed water, boiler feed water and potable water, through a series of unit operations. These unit steps included clarification, media filtration, reverse osmosis and ion exchange. PROXA also optimised the plant to cater for fluctuations in feed water composition related to seasonal changes.
“ Given PROXA’ s experience in operating in challenging conditions with limited resources, we were able to increase the plant availability and decrease the operating costs associated with chemicals and consumables by more than 30 %.”
The Neves-Corvo mine located close to Castro Verde, in southern Portugal, operated by SOMINCOR( Soc Mineira de Neves-Corvo), a subsidiary of Lundin Mining, is getting a new water treatment plant. Neves-Corvo is the biggest copper and zinc mine in the European Union and has been in operation since 1988.
The mine was one of the first plants to adopt thickened tailings disposal( TTD), installing an
