The main are Sulphuric Acid and Anode Slime
(material rich in precious metals such as gold and silver).
* ANTAM, PT Smelting and PT Freeport Indonesia Sign Memorandum of Understanding Regarding Project Development of Anode Slime
Processing & Precious Metal Re7nery
Specific topics include the effect of crack opening on the distribution of magnetic flux density around fatigue cracks, a hydrometallurgical pre-treatment process for recovering valuable metals from lead anode slime
, mine tailings reprocessing in Da-Hongshan, optimizing the operational performance of diesel mining trucks using thermal management, a new fast multi-pole boundary element method for solving three-dimensional elastic problems, and removing boron from metallurgical-grade silicon by refining the slag with the yttria-silica system.
The smelter also produces side products including 655,000 tpa of copper slag; 1800 tpa of anode slime
; 92,000 tpa of sulfuric acid 35,000 tpa of gypsum.
The entire by-product, namely copper anode slime
, is exported as no metal recovery facilities are available locally.
In the third polishing filter application, the wash water is filtered to remove anode slime
The characterization papers present new approaches to assessing the behavior of gold in copper anode slimes
, kaolinitic clay, pyrite powder, aluminum 6063, diamond composites, and reinforced polyester composites.
