TIN WASHING
Tin obtained from the mining process, will be processed to a washing plant to obtain tin that is separate from other minerals obtained in the mining process.
REFINED TIN PRODUCTION
Tin obtained from tin washing will be further processed. In the process mineral dressing, other minerals will be separated so as to obtain tin ore with levels that meet the smelting standart. the process of increasing the ore conten is carried out to obtain the final product in the form of hight quality refined tin with high Sn content and low impurities.
After tin ore with has high Sn level is obtained, then proceed to the smelting process. The smelted refined tin then goes through a refining process. The smelted refined tin then goes through a refining process using crystallizer and electrolytic refining to obtain high quality refined tin and low lead content (Pb).
The results of this process are bar or rod-shaped refined tin that has a weight scale ranging from 23kg to 27 kg per bar. The refined tin produced by PT TIMAH Tbk has a trademark registered on London Metal Exchange (LME>
100% of tin products are ISO 90001 : 2008 certified, reinforcing PT TIMAH Tbk Commitment to the application of best standards and quality throughout the entire production process.
