THE CHALLENGE
Founded in 2011, Mission Point Mining (MPM) is now a major player in the South African sand production industry and employs 30 people on its mining site in Sasolburg.
The company formerly used a bucket wheel system to wash their product however they were only getting approximately 90% pure silica sand from the wash plant and losing fines. Additionally, the sand was wetter and drying times were affecting the level of output and company efficiencies.
Given the location, the site experiences issues with access to large volumes of water due to government regulations therefore the need to acquire a water recycling system is also necessary.
THE SOLUTION
It simply took a visit from CDE to the MPM offices in 2012 to start a conversation on how to maximise production with cyclonic sand washing. As CDE representatives are based locally, there are no communication or time zone barriers.
Smart water management
Working with CDE, MPM installed a CDE EvoWash™ and CDE AquaCycle™. The EvoWash™ 151 processes 90-130tph. To run the EvoWash™, MPM feeds the plant up to 500,000 litres of water per day for a total running time of 11 hours.
To ensure optimal efficiency, the company has put in place highly effective water saving systems benefiting both the business and the environment.
The CDE AquaCycle™ saves up to 90% of waste water whereby MPM’s water recovery system for stockpiles is also instrumental in accelerating the drying process of the end product so that it can be sold quickly to make space for new stockpiles.
THE RESULTS
Since Mission Point Mining switched to the CDE cyclone and water recycling technology, demand for its products has grown to the point that the company expanded their business and explored the best value for money solutions to increase sand production on its mining site.
Johann Pretorius, Managing Director of MPM comments: “We’re one of the few producers who put the effort in and recycle every drop. We are proud of it as we are living proof that in the materials washing sector, being environmentally responsible also makes complete business sense, especially in countries that are vulnerable to drought.”
“Swapping our bucket wheel for a CDE EvoWash™ and AquaCycle™ has been a great investment. We have had no regrets making this decision. The sand quality achieved thanks to the CDE equipment has generated such a boost in demand for our product that we now need to expand our operations.”
“An additional advantage is that we have been able to commit to safer operations as CDE equipment is a high-tech system which is simple to use. Together with well-conceived safety details this guarantees a comfortable working environment.”
“Quality-wise, we are the best. Looking ahead to the future we will add more CDE equipment to meet our rising demand and ensure service excellence.
Stockpiles used to dry for days before being sold but thanks to the CDE water recovery system our product can now be sold within hours.”
Ruchin Garg, Regional Manager, CDE added,“Also, with the installation of our stockpile dewatering system under the main 0-1mm stockpile, the customer produces a sand with below 8% moisture almost immediately, which makes handling of the sand easier and allows for very high savings on drying costs when preparing the product at the company’s drying facility for specialist sands.”
