Promining

Promining is a corporate group made up of several specialized production entities, anchored by two major companies: PT Xpertum Henze Karsa and PT Xpertum Metalon Karsa. We deliver end-to-end mineral processing and smelter engineering solutions—from early concept to full turnkey execution. Our team leaders have been educated and trained in Germany, and we are backed by DEKRA-certified experts to ensure strong quality management and international standards. Our close ties to Germany in metallurgy and mining engineering bring a distinct, practical perspective to every project. What we do: Plan, engineer, and build turnkey smelter systems Design and optimize mineral processing flowsheets and process routes Audit and improve existing smelters built by third parties, including troubleshooting, restructuring, and performance optimization This last point is one of the most common needs in Indonesia, where smelter systems are often built under time pressure and without sufficient preparation—leading to unstable operations, inefficiencies, and costly downtime. Our approach: We are miners—so we think and execute with an operator’s mindset. Our solutions are practical, grounded in state-of-the-art mineral extraction technology, and strengthened by our own innovations and process know-how. If you ask us for solutions, we deliver systems that work—reliably and sustainably.
