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.

Rcovery of gold in pyritic ores Mine Engineer

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Etching (microfabriion) Wikipedia

Etching is used in microfabriion to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching.

Microwave heating of gold ores for enhanced grindability

Research highlights Microwave heating of a material leads to microcrack formation. Microcrack formation allows size reduction and liberation at a lower stress level. Microcracks generated enhances access of lixiviants to the mineral of interest. Microwave processing enhanced grindability and cyanide amenability of the gold ore.

Color Negative Film Processing Errors micro.magnet.fsu.edu

The stability of chemical solutions is also a factor in color processing, because sensitive combinations must be mixed immediately prior to use to avoid rapid deterioration of the components. In general, the shelf life of diluted color process chemicals is far less than those used for black & white film processing.
