Procedure Residual Copper Soluble Analysis -Assay Method -Acid

METHOD for SEQUENTIAL AND RESIDUAL COPPER ANALYSIS PURPOSE: To determine, through sequential dissolution, the probable copper distribution by copper mineral in a sample. SCOPE: Matrix: Copper ores Analyte: Copper (Cu) Range: <1-20%. Accuracy/Precision: This method is not intended to be accurate since there is not one standard procedure for the determination of non-sulphide copper.

copper sequential leaching method

Sequential or diagnostic leaching (DL) is an important procedure used as a diagnostic tool to establish the exact location of copper minerals. This multi-step ambient leaching procedure is a crucial tool when dealing with variability in deposits with complex copper mineralogy.

Traditional copper diagnostic leaches use sodium cyanide and sulfuric acid as leach reagents, with the dissolution of the copper sulfide mineral in these media being expressed by Eqs (2) and (3), respectively. The exact mechanism of these equations will vary according to the copper sulfide mineral and reaction conditions.

Diagnostic Gold Analysis. In order to determine the nature of the gold occurrence and associations within the ore; we do a multi-stage diagnostic analysis where a 1 kg portion was ground to a nominal grind P80 of 150 um and subjected to a sequential gold extraction test. Test conditions, assays and mass balances are supplied below.

Results showed that up to 85% of copper recovery from chalcopyrite could be achieved using A. copahuensis. Improvements in these yields are intimately related to an early contact between cells and the mineral surface. On the other hand, surface coverage by inactivated cells as well as precipitates significantly reduced copper recoveries.

The analysis of Cu distribution in pre-treated mine tailings after electrodialytic remediation was carried out by using two methods of sequential extraction. The initial content of copper in the tailings was 1109 mg Cu/kg of dry tailing, where close to 40% of the sample in weight corresponded to a soluble fraction. The tailing was treated with a leaching solution for 24 h.
