:: How Mine's ACACIA Reactor Pays Handsome Dividends

Independence Gold Mining (Pvt) Ltd, Zimbabwe's largest gold producer, has demonstrated their confidence in the long-term future of the mining industry by investing in the latest mineral processing technology to boost local production. Independence Group's flagship How Mine, ordered a ConSep ACACIA Reactor after promising pilot trials indicated +99% gold recovery from high-grade Knelson concentrates.

Since installation, the ACACIA has achieved a payback of less than one month, inclusive of a year's worth of reagents. The impact upon overall mine recovery has been a profound increase from 88% to 91%, a real bonus towards the mine's enhanced viability.

Mike Marriott, Independence Group's Managing Director says they are extremely happy with the performance of the ACACIA. "Not only have we seen improved efficiencies, this technology has enabled us to discard the use of mercury for amalgamation of gold in concentrates, thereby achieving a great advance in our strategy of eliminating environmental and security risks. This investment demonstrates our commitment to the business of gold mining in Zimbabwe, and we continue to believe that given the appropriate economic dispensation, gold mining will prove to be one of the industries that will lead an economic turnaround in this nation."
