Overview
The Marikana Operation, which includes Western Platinum Limited and Eastern Platinum Limited, is an active mining complex located in the Marikana district, 40 kilometres east of Rustenburg in the North West province of South Africa. The primary commodities produced are Platinum Group Metals (PGMs), including platinum, palladium, rhodium, and gold (referred to as 4E PGM), as well as iridium, ruthenium, nickel, copper, and chrome. The mine is a large, established, shallow to moderate depth PGM complex.
Production
679,245 ounces of 4E PGM for the year ending 31 December 2024; combined fresh ore milling capacity of approximately 600,000 tonnes per month.
Processing
Ore mined at Marikana is processed through four of the eight available concentrators, which have a combined fresh ore milling capacity of approximately 600,000 tonnes per month. The resulting concentrate is sent to the on-site smelter, which has five furnaces, to produce a sulphide-rich matte. This matte undergoes further processing at the Base Metal Refinery (BMR) where nickel and copper are extracted. The final PGM-rich product is then sent to the Precious Metal Refinery (PMR) in Brakpan for final treatment to produce refined precious metals.
Equipment

The facility uses Rotary Kiln Electric Furnace (RKEF) technology to convert high-grade saprolite nickel ore into ferronickel. Additionally, High-Pressure Acid Leaching (HPAL) plants process low-grade limonite ore into materials for electric vehicle batteries. Nickel slag, a by-product from the RKEF smelters, is recycled to produce materials like bricks and concrete mix for use within the operational area.
Expansion
PT Karunia Permai Sentosa (KPS) is developing the third RKEF smelter, which is currently under construction. This project is projected to have 12 production lines with a total capacity of 185,000 tonnes of nickel content in ferronickel per year. The first phase, consisting of four lines with a capacity of 60,000 tonnes, was expected to begin operations in the first quarter of 2025.
