The impact of platinum production from UG2 ore on ferrochrome production in South Africa by L A Cramer* J Basson† and L R Nelson Synopsis South African platinum mines produce the world's majority of platinum metal that is used in autocatalysts and jewellery As the platinum market is forecast to grow at healthy rates into the future the South African producers Anglo Platinum
nickel ore deposits are closely associated with mafic and ultramafic in trusive rocks and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle
