Platinum producer implements technology to reduce SO2 emission

The implementation aims to ensure that operations meet air quality standard targets set by international best practice standards

Anglo American Platinum has started a project to reduce sulfur dioxide SO2. It will implement the new Moist Sulfuric Acid (WSA) technology in the smelter, which is expected to reduce SO 2 emissions by about 96%. Construction is expected to be completed by the end of 2020.

The company began seeking technical solutions for SO 2 reduction at its Polokwane smelter in North Africa in 2010. The proposal is to regularize the situation in accordance with the implementation of the New SO 2 Minimum Emission Standards by Department of Environmental Affairs.

The WSA process captures SO 2 gas from the furnace and converts it to sulfuric acid. This will be the first time the technology has been employed in the Platinum Group Metals (PGM) electric furnace to produce high strength acid. This technology has been selected from forty different technologies due to its suitability for treating gas with the level still in the foundry.

Anglo American Platinum CEO Chris Griffith said the group is striving to continue minimizing environmental impacts through innovative approaches, recognizing the value and scarcity of natural resources. According to him, this technology “will ensure that operations meet the Group’s air quality standard targets as well as international best practice standards.”

According to him, “there is a broad partnership with industry, government, civil society and communities to address environmental challenges and ensure a sustainable future for all.”

The investment amount to develop the Polokwane smelter reduction project is $ 1.57 billion and will create about 500 jobs, will work for about 14 companies and provide full time jbs to 30 people. Since 2013, Anglo American Platinum has had an excellent track record of environmental compliance, reporting no significant environmental incidents.
