Gold Recovery with Centrifugal Gravity Concentrator
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as […]
Analysis for (Cu, Pb, Zn, Fe, Cd) by ATOMIC ABSORPTION
Sample Preparation for assaying Copper/Lead/Zinc/Iron/Cadmium by AA: Weight 0.1 – 0.25 g of sample into a 300 ml tall form beaker Add 5 ml Conc. HCL + 5ml Conc. HNO3. Place samples on a padded hotplate in a fume-hood. Turn the hotplate from 1 switch to 2 switches. Bring to dryness. Avoid sample spitting by […]
Copper Lead Zinc Metallurgy
Monthly composites of mill feed, copper concentrate, lead concentrate, zinc concentrate and final tailing were sent for detailed mineralogical/metallurgical analysis. These samples were analyzed and also compared to previous similar work done. The samples represented the following flowsheet and monthly balance: Mineral Speciation: Although Chalcopyrite is still the main form of copper in all samples; […]
Flotation pH vs Collector on Pyrite/Galena/Chalcopyrite
Gold Gravity & Flotation Circuit
Arsenic in Copper Concentrate
In a certain case study of “high” Arsenic in Copper Concentrate (almost 0.5% As) produced by flotation, and where the Cu Conc is mostly chalcopyrite and therefore the main form of copper; the content of secondary copper minerals was variable. Tennantite/Enargite/Freibergite, a copper-arsenic sulphide mineral, as well as covellite, was present in significantly higher amounts today. […]
Flotation Reagent Mix Concentration Strength
Just an example of strength at which flotation reagents can be mixed at in a Concentrator:
XRF Sample Preparation Methods/Procedure
What is x-ray fluorescence and why is XRF sample preparation is important for correct XRF analysis. This is a little introduction to some of our instruments; from left to right we have the X-MET7000 series these hand held analyzers are great for their versatility and portability, the X-Supreme in the middle is used for bulk analysis […]
X-RAY Fluorescence Spectroscopy
Here I will be focusing on a chemical surface technique called X-ray Fluorescence Spectroscopy, this method is of importance because it is widely used for chemical analysis particularly in investigation of different materials and research in forensic science this will be vital in solving criminal cases. This technique will be described on the chemical and […]
