Cheap & Undervalued Gold Mining Stocks
Some of the Best & Most Undervalued Gold Mining Stocks can be defined for having low or cheap valuations coupled with poor trading performance in being closer to its 52 Week Low. The share price performance, where a company trades between their 52 WH and 52 WL, of the precious metals (gold and silver) universe is […]
Flotation Kinetic Rates & RTD Analysis Evaluation
Every mill operator, metallurgist or not, needs to understand the Flotation Kinetics and Flotation Rates taking place within his plant’s circuit. A simple case study of a very basic process flowsheet (ball mill grinding to conditioning, followed by rougher/scavenger and 2 stage froth flotation cleaning). This very basic and practical study of Froth Flotation Kinetics […]
Zinc Sphalerite Activation & Conditioning Time Effect of CuSO4 Copper Sulphate
The most effective, and really only way for recovery of zinc sphalerite by froth flotation is by first activating the mineral with CuSO4 (Copper Sulphate) and allowing some conditioning time. How much time is optimum for effective zinc activation and good froth flotation? Obviously the answer to that is dependent on the test sample’s mineralogy, […]

Gold Prospector – Mineralogy and Microscopy for Prospecting
Small Gold Prospectors, Miners and Processors needing simple DIY mineralogy or microscopy work can take advantage of the fact that a gold shaker table behaves as some kind of a classifying device and view their gold sample directly under a microscope without all the preparation work. You can take any of your Prospecting products and look at […]

Size by Size Microscopy & Optical Mineralogy – Best Portable Microscope
Basic mineral processing troubleshooting often requires you to obtained at least the most basic Mineralogical or Microscopy imagery data on a Size by Size base. If you are a metallurgist for a large Mining Company, you can go ahead and spend big-daddy’s money ( $5000 per sample) but if you are just a little guy […]
Compare X-Ray to Laboratory Analysis
If you run a standard assay laboratory analysis you might wonder if an XRF Spectrometer could provide enough precision or accuracy on some of your less important samples (production geology for example). What about an XRF vs AA comparison? What is an XRF’s Measurement Reliability & how does an X-Ray/XRF compare to a laboratory? I once ran […]
Gold Prospecting
Gold prospecting seeks to find new gold deposits. Gold is typically found in placer deposits or in hard rock deposits. The type of deposit dictates the methods used to explore for them. Mineral exploration on a budget can be successful if you understand the basics of geology. Gold Prospecting in Placer Deposits Placer deposits are […]
