Collectors Strength – Xanthate Family – Recovery Power
A little about collector strength and Xanthates: Some call it selectivity, I call it “how much do you put on”. Even the most selective collector can be rendered un-selective it you add enough. In reverse order of strength (strongest to weakest): PAX SIBX SIPX SEX Methyl Xanthate (uncommon) More about the collecting power of xanthate and […]
Process of Cyanide Gold Extraction
Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99% sulphides of which 10 to […]
High Tech Flotation Reagent Addition System
Flotation Reagent Metering Pumps
I recently did a reagent plant trial and worked with a pretty nice flotation reagent metering pumps. The pump is supplied by https://www.pmps.co.za This portable reagent supply unit is a mechanical diaphragm metering pump. As see on https://www.pmps.co.za/obl-mechanical-diaphragm-dosing-pump They even had “Water Driven Pumps” Other pumps I never worked with include https://www.awe-ltd.co.uk/products/dosing_pumps_electronic.html and https://www.lutzjescoamerica.com/index.php?id=1645 Also https://www.911metallurgist.com/mibc-frother-pump
Itronics will update the procedures used in Au-Ag-Cu mines
The company Itronics Inc. has recently announced it’s updating its technology developments and plans “with a focus on potential applications for silver-gold mines that have a silver to gold ratio exceeding 4 to 1 in the ore”, it’s possible to read on the firm’s website. According to the Nevada-based business, its technology may also “prove to […]
Sodium Metabisulfite MBS for pH Control and Pyrite Depression in Flotation
Sodium Metabisulfite aka MBS is used for pH control in froth flotation to control Pyrite depression. Below is a graph showing pH VS pyrite recovery at various collector addition rates. It is also used to prevent flotation of sphalerite by copper activation in the presence of Tennantite/Covellite in the ore. For pyrite flotation, you see maximum iron/pyrite […]
Compare Hydroxamate AM2 Rinkalore CTC3 Oxide Collectors
In this series of tests aimed to Compare Hydroxamate Collectors namely: AM2 Rinkalore and CTC3 we now conclude. All data indicate the CTC3 is a more selective reagent. In all tests, metallurgy was improved. Nowhere were the results produced by CTC3 inferior to AM2. Although AM2’s Lab Recoveries can look “attractive”, the AM2 reagent shows problematic […]
Oxide Flotation Collector | Collector for Copper Oxide Ore
In this flotation tests and evaluation for the best collector for copper oxide “ore” 911Metallurgy continues with material that’s 60% Oxide copper. Sample C: 1.7% Copper about 60% Oxide Cu Rougher Tests: Both reagents appear to behave similarly as the “blue dots” are seemingly a continuation of the trend started by “red dots”. Oxflo and Axis […]
Flotation by Hydroxamate: OXFLO- CTC vs AXISHOUSE-AM2
The order of Hydroxamate flotation testing was first OXFLO for 3 days, then AXISHOUSE’s tests were performed 3 weeks later for 7 days. The results of each “Ore Type” or Samples tested by OXFLO (OxF) and AXISHOUSE (AH or Axis) is graphically displayed and evaluated in this report. Prior to testing their chemicals, each “Ore […]
Hydroxamate for Copper Oxide Flotation
Here is a comparison of two Hydroxamate Collectors used for the flotation of Oxide copper, namely CTC3 from OXFLO and AM2 (AKA Rinkalore) from AXISHOUSE. This report contains a comparison of the scoping test-work done by both suppliers to determine which one is the best Oxide Collector . Test Summary #1 Flotation by Hydroxamate: OXFLO’ […]
