Case Study: Barrick Gold

Barrick Gold

Background to the challenge

Barrick Gold is the world’s largest producer of gold. With mines operating across five continents, they control some of the most prolific mineral reserves on earth.

In 2013, Barrick produced 7.17 million ounces of gold. The company has met its gold production guidance for 11 years in a row.

The problem

Barrick had operational concerns about their HV wash pad. The pad's oil water separator was not discharging consistently and was often blocking due to an ingression of sludge.

In line with their environmental discharge obligations, the company needed to adhere to a 10ppm hydrocarbon discharge standard. Any new equipment would need to be retrofitted to the existing wash bay – and ensure Barrick avoided costly downtime during installation. In addition, the solution would need to be reliable enough to ensure long-term insulation against shutdowns and fines.

What Cleanawater did

Calling on decades of expertise in mining wastewater treatment, Cleanwater identified a hydrocyclone oil water separator as the ideal solution.

So we installed our DEOIL10 hydrocyclone system with a treatment rate of 10,000L per hour. This would ensure waste water was properly treated prior to being discharged into an evaporation pond.

The new system enabled the removal of gantries installed to support the previous oil water separator. That meant pumping-out and maintenance would now be less costly and less time consuming – giving Barrick a significant ongoing saving.

Retrofitting the system to the existing wash bay meant a quick install – saving on costly downtime. The result was a low-maintenance, low-cost water treatment solution that fit the brief perfectly.
