Naphthenic acid with acid number of 100200 mg KOH/g could be used to extract yttrium in the system of 20 naphthenic acid + 20 n butanol + 60 n hexane. A transparent and uniform phase was formed during saponification but did not influence the extraction process. n Butanol and n hexane could shorten phase separation time and lessen emulsification. Excess naphthenic acid

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores 1114, but is introduced here because an important by product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
The extraction of naphthenic acid from low grade crudes offers economic and environmental advantages over chemical conversion or other separation processes. The properties of the solvent play critical roles for the successful implementation of the extraction process.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated concentrated. The processing

The term naphthenic acid has roots in the somewhat archaic term naphthene cycloaliphatic but non aromatic used to classify hydrocarbons. It was originally used to describeplex mixture ofm based acids when the analytical methods available in the early 1900s could identify only a few naphtheneponents with accuracy. Today naphthenic acid is used in a more generic

In order for this acid can be analyzed in the period in which occurs the extraction of oil is used a technique that evaluates the content by titration with KOH, originating the naphthenic acid number or index. This index is used to analyze the content of the sample, but corrosion does not interfere with the quality of the oil and the nature of acids present fields, 2005.

N2 The formation of different types of naphthenate deposit during production operations isg an increasing flow assurance problem for the oil industry. Two end member types of
Copper naphthenate can be synthesized by any of three methods, but themercial process is fusion of naphthenic acid with copperpounds such as basic copper carbonate, copper hydrate, or copper hydroxide. The latter two reactants generate only water as a by product, while the former generates water and carbon dioxide.
