The ore chosen was a partly-decomposed porphyry, extremely siliceous and ...
Proper chlorination and filtration give pool water its clear, sparkling appearance. Chlorine exists as a solid, a liquid and a gas. The strength of each type is determined by the amount of chlorine within the material that is effective both as a disinfectant and an oxidizer. 1.
Because of increasing ecological concern, the Bureau of Mines is investigating the use of chlorination technology in extractive metallurgy. A key problem is the fact that ferric chloride is commonly generated during processing of a wide variety of ores and minerals. This paper describes small ...

Gold Ore Chlorination Mineral Processing Metallurgy. Experience has shown how difficult it is to obtain information regarding laboratory tests in connection with the gold ore chlorination process for the extraction of gold from its ores, and I therefore present the following method, somewhat in detail, for the benefit of those who may desire to pursue research work in this field.
The kinetics of chlorination of alumina and bauxite with CO/CI2 mixtures were studied in the range 300-1100°C. The temperature of prior calcination is critical in determining the reaction rates. An optimum chlorination temperature in the range 600°C-750°C was demonstrated such that there is no increase in reaction rates with increasing temperature.
Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
A thermodynamic analysis of chlorination reaction of iron, present as an impurity, using HSC Chemistry for Windows 5.1 (HSC, 2003) was made. Thermodynamics calculations for the reaction of iron oxide and hydroxide phases from the mineral with chlorine show that chlorination is thermodynamically feasible at temperatures above 1000 °C. Eq.
Fundamental thermodynamic and kinetic data are reviewed to identify optimal processing conditions for high-temperature gold chlorination systems. Chlorination of ores to identify viable complexing agents and to provide empirical extraction data is then discussed. Finally, several promising areas for ...
Nov 10, 2009 · Conventional mineral processing cannot modify the composition of chromite. This composition can be modified only by using chemical or thermal methods. This section is devoted to the thermal treatment of the chromite concentrate to increase its Cr/Fe ratio through selective chlorination and oxychlorination of iron compounds.

To assist in overcoming these losses, chemical methods were quickly devised to extract gold from the mineral. Chlorination proved to be a successful lixiviant and quickly became popular as a treatment method, with most of the large independent mills around Cripple Creek mills using chlorine by 1898.
