Ready-for-export tin ingot produced by PT.MSP contains 99.90 % of Sn, with ISO Certification and SUCOFINDO Inspection.
United Enterprise Ltd. is holding Mining Authorized for Onshore and Offshore with mining territory Bangka Belitung Island that known as Indonesian Tin Belt. The Smelter and Marketing Office are located in Bangka.
Processing and smelting of tin ore which is done by United Enterprise Ltd. through the mine had levels between 30-65% Sn and tin ore processed laundering section, with the aim of the separation of other minerals and enhanced levels of Sn up to 70-72% and as one of the main requirements of fusion . The process of increasing concentration of tin ore from mining is required as a final product in the form of tin metal with a high Sn content and the expected low content of impurities.
The next process is smelting tin ore into tin. To produce a metal tin with a high quality with high levels of timbale (Pb) is low purification process is carried out in advance using a special tool that is crystallizer and electrolytic refining. We produce tin in blocks weighing approximately 15 to 30 Kg per beam. The quality divided based on the main minerals content that called Cassiterite (SnO2).
Our Tin Material Quality contain of Sn 99.85 up to Sn 99.95 equipped with ISO Certification and SUCOFINDO Inspection. Our Products includes Pure Tin Ingots, Tin Alloy and Lead Ingots.
