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.
Copper slag is use din cement and concrete production, anode slime in the process of refining gold and silver, and sulfuric acid is widely used in fertilizer industry and gypsum is a feedstock for cement.
PT Unsanitary Smelting also plans to build a smelter in Bontang, East Kalimantan to produce copper cathode and copper slag, as the main products with gypsum, sulfuric acid, and anode slime as by products.
The entire by-product, namely copper anode slime
, is exported as no metal recovery facilities are available locally.
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.
In addition, the new plant will produce, as a byproduct, approximately 340 TPY of de- copperized anode slimes
containing significant amounts of silver.
Smelting produces copper cathode, Anode Slimes
, Copper Slag, Copper Telluride, and by products of Gypsum, and Sulfuric Acid.
