Be brave enough to embrace beneficiation, SA president tells mining companies

08 february 2019

South African president Cyril Ramaphosa has implored mining companies to embrace beneficiation as it encourages the expansion of industrial capacity, create employment and enable the extraction of greater value from mineral wealth.
He told delegates at a mining conference in Cape Town on Tuesday that most mining companies used to treat beneficiation as a swear word.
“They used to say we are miners and not [into beneficiation],” Ramaphosa said.
“Be brave enough and courageous to embrace beneficiation, let it not be a swear word [anymore].”
He said several companies had seen the logic of local beneficiation and were keen to work with government to develop downstream industries. 
South Africa hosts the world’s largest reserves of platinum group metals and manganese, and some of the largest reserves of gold, diamonds, chromite ore and vanadium.
The country’s minister of mineral resources Gwede Mantashe told the same conference on Monday that the decline in local jewellery manufacturing and diamond beneficiation was due to red-tape.
The country’s cutting and polishing industry had declined from a peak of 4,500 two decades ago to as low as 300 in 2018.
South Africa produced 9,68 million carats in 2017 at an average price of $319 per carat, according to the Kimberley Process.
