Johannesburg - The notion that plants, in this case wheat, can be used to extract gold from mine dumps seems so far-fetched it’s mind-blowing.
Yet that’s exactly what the research of vivacious and eloquent Tshiamo Legoale, the daughter of a single mother, Barati Legoale from Mogwase near Sun City, has established.
It’s called phytomining. The wheat is planted on dumps and enzymes found in its roots make the gold soluble.
