Metallurgical Advances and Their Impact on Mineral

Advances in heap leaching have vastly improved the economics of low-grade oxide gold and copper ores. Depending on scale, site characteristics, and metal price, the average break-even ore grade for heap leaching is approximately an average of 0.025 oz of gold per ton (oz/t; 0.78 g/t), compared to 0.06 oz/t (1.87 g/t) for milling (fine grinding and agitated cyanidation).

HPLC Advances for Better Separations

Refining particle technologies Both HPLC and UHPLC continue to benefit from advances in particle technology. Fused-core, solid-core and core-shell particles—consisting of a solid core fused to a porous outer layer—improve efficiency by reducing the diffusion path length of molecules traveling through the column and also allow better separations at lower flow rates and pressures.
