Processing High-Grade Concentrates from Challenging …

10%On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how …

Hydrothermal Sphalerites from Ore Deposits of Baia Mare Area

The high iron content of the sphalerites in the gold ore deposits in the Săsar area could be formed at high f S 2 which explains the lack of tellurium and the presence of native gold. If the temperature remains relatively constant, the boiling of the fluid will lead to loss of sulfur gas, meaning a decrease in f S 2 .

Black Sands Processing « TCB Metals and Refining

We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.
