Apr 07, 2020 Apr 07, 2020 The solubility of copper depends on the nature of the copper compound and the solvent used. In its metallic state, copper is soluble in nitric acid and sulphuric acid at a high temperature. Some copper salts are soluble in water. The copper compounds that are soluble in water include copper chloride, chromite, formate, fluoride and gluconate

or acid soluble copper assay with the total copper assay has typically provided a good indication as to the distribution of copper oxide mineralization within a deposit. However, the same analytical procedures do not provide an indication as to the presence of any secondary or leachable sulfide mineralization

Typically copper analysis is dependent on whether the requirement is for total copper content or acid soluble copper. Some labs will digest using mixed acids but excluding HF. The final determination will be by short iodide titration or AAS/ICP-OES. Other operations will add HF and then complete with titration or AAS/ICP-OES

Copper may occur in natural waters, wastewaters, and industrial waste streams as soluble copper salts or as copper compounds precipitated on suspended solids. Forms of copper in water can be classified as insoluble, dissolved (free and complexed), and total recoverable. Insoluble copper includes precipitates such as copper sulfides and hydroxides

Copper recovery is related to all of these events. This study presents information on acid consumption of various gangue minerals as well as data for copper recovery from an associated copper ore. INTRODUCTION Acid consumption during copper leaching of oxide ores is a very important issue. Acid consumption can determine whether or not a

The higher the acid-soluble copper (AsCu) feed grade, the higher the observed improvement (Figure 2). The additional recovery was only around 2% when the AsCu feed grade was lower than 0.2%, but was observed as high as 15% when the AsCu feed grade was higher than 0.6% (Figure 3). Figure 1. Refloating tails with and without reagent addition

Soluble in ammonium hydroxide; in hydrochloric acid forming copper(I) chloride which dissolves in excess hydrochloric acid; with dil sulfuric acid or dil nitric acid the cupric salt is formed and half copper is pptd as the metal

Feb 08, 2018 DCH-024 intersected 0.85% total copper over 95.95 meters of which 0.75% copper reports as soluble copper, including 3.16% total copper over 6.15 meters of which 3.01% copper reports as soluble copper

Sep 08, 2020 Recoveries exceeded acid soluble component of total copper in virtually all samples, some by significant margins, indicating a larger proportion of the copper is acid soluble

Oct 22, 2011 In oxide copper deposits, the acid soluble copper represents the fraction of total copper recoverable by heap leaching. Two difficulties often complicate the joint modeling and simulation of total and soluble copper grades: the inequality constraint linking both grade variables and the sampling design for soluble copper grade, which may be preferential and cause biases in sample statistics. A
