A study should be made of the structure of the ore-bearing limestones, with the special object of determining the causes that have made certain strata
Calculation of the Theoretic Reducing Powers of Various Organic and Inorganic Mineral Substances usually Occurring in Association with Ore-Deposits, Based upon the Weight of Oxygen
Carbon has long been recognized as one of the most powerful reducing agents in the deposition of ores. Investigations, made by myself, of the zinc-
Experiments made by the author on the oxidation of petroleum show that the heavy hydrocarbon oils unite very slowly with oxygen, when first exposed to
Carbonic acid when combined with a base is a weak acid, readily displaced by a stronger, as sulphuric, hydrochloric or phosphoric acid, and also by
Occurrence of Carbon combined with Hydrogen: Blende and galena have been deposited in coal in the outlying basins of the Coal Measures, scattered along the broad,
Rich deposits of blende, formed in great part by the secondary enrichment of smaller, or less mineralized, primary ore- bodies, are found near the surface
In mining-regions where the ores occur in limestone, it is observed that in most instances the largest and most productive mines are in belts or
Definition of Solvent Extraction: The unit operation “solvent extraction” is applied in many industries, and has several different forms. For instance, for the recovery of many
The development of solvent extraction processes over recent years has led to their application on an increasing scale in metal extraction plants. The author’s company
