Does South Africa want to ban Ferrochrome as well or just chrome ore? If it's just chrome ore that they want to ban because they prefer to make money through the beneficiation process to ferrochrome  rather than leaving those profits on the table for China to scoop up, then there wouldn't be a problem.... as long as South Africa has the capacity to produce an adequate and stable energy supply for that energy-intensive process...

Remember this post:

JOHANNESBURG (Reuters) - Chinese investors signed agreements to build a $10 billion metallurgical complex in South Africa ...The complex, which is still in the planning stage and envisages building a stainless steel plant, a ferrochrome plant and a silicomanganese plant, is a much-needed vote of confidence in the sputtering South African economy...

 The South African SEZ (Special Economic Zone)  plans to house plants with a capacity of 3 million tonnes per annum of stainless steel, 3 million tonnes per annum of ferrochrome and 500,000 tonnes per annum of silicomanganese. Those capacity targets are subject to change and will be finalised by the end of the year, the executive said."
