about us


Transalloys is a well-recognized supplier of silicomanganese globally, and the largest silicomanganese producer in South Africa. The production plant is situated 14 km west of eMalahleni and approximately 90 km east of Pretoria, in the Mpumalanga Province. Manganese ore used in the production process comes from the Northern Cape Province of South Africa which is known to contain 75% of the world’s identified manganese ore reserves.

The company was established in 2007 when the Renova Group, a Russian diversified investment holding, acquired the plant. Since 2018 Renova,decreased its effective interest in Transalloys to below 25%. Today more than 51% shares in Transalloys are held directly by Swiss and Israeli investors.

The Renova Group acted as an important locomotive for Transalloys development - under its strategic leadership and as a result of the concerted efforts by the Transalloys’ management team and the employees, the productivity and output of the plant were increased by 50% from what it was at acquisition. Our current production capacity is approximately 165 000 tonnes of sillicomanganese per annum.

The standard grade silicomanganese contains 15.5 to 16.5% of silicon, 65 to 67% of manganese and a maximum of 2% carbon. SiMn is used, inter alia, as a grain refiner and for de-oxidation in the steel manufacturing process. Transalloys’ products are recognised internationally for quality. We are ISO -9001:2015 listed. We produce low phosphorus SiMn which is a preferred product by many end-users.

Transalloys’ business is built on our values of integrity, excellence, teamwork and commitment to continuous improvement and innovative thinking. Our vision is to become a benchmark in the manganese alloy industry through our people, adaptability and perseverance.


Transalloys utilises 5 submerged arc furnaces to produce SiMn.

The submerged arc furnaces comprise of two 48 MVA semi-closed furnaces and three 18 MVA open furnaces. Raw materials are fed from a common raw material handling system into three sets of day bins, from where the individual furnace recipes are batched and conveyed into the furnace bins.

The furnaces are tapped at regular intervals and the alloy is separated from the slag before being cast into layer casting beds. After a cooling down period of ± 3 days, the material is removed from the casting beds and fed into a crushing and screening plant. The different size fractions are separated and stockpiled or dispatched to ports for export, or collected by local customers.


At Transalloys we are aware that our activities could have an impact on the environment. In this regard we aim to fully comply with all legal requirements. In addition, all process changes, upgrades and refurbishments are carried out with consideration of the impact of the changes, in order to mitigate or eliminate the environmental impact. Our comprehensive environmental management plant guides future capital expenditure in order to ensure that our impact on the environment continues to reduce.

Transalloys is compliant to the ISO 9001, ISO 14001 and OHSAS 18001 international Standards. Transalloys is also the owner of one of the first CDM (Carbon Reduction Mechanism) projects in South Africa. During the past 5 years, huge improvements in efficiencies gave rise to a considerable reduction in carbon emissions per tonne of product produced.
