Effect of Flotation Density on Grade and Recovery
In an effort to test the Effect of Flotation Cell Size in Laboratory, I ended up with a test for the effect of flotation density on grade and recovery. Therefore, I here present is a Laboratory experiment that counters the reality of a full scale industrial flotation plant. By “counters the reality” I mean, larger commercial cells do not give better
Processing Gold by Cyanidation Leaching
Processing Heap Leachable Gold Ore by Cyanidation Oxide ore (low grades) will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH. Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction. After the leach cell is harvested,
Falcon Gold Tracker -MD20 Reviews
As to review its applications, in particular the Falcon Gold Tracker MD20 has been used successfully on diamond drill core and detected pinpoints of gold. While it is finicky and the probe head has to be in direct contact with the core, it is effective. The microscopic gold has then been checked with a 20X, internally lit hand lens

Geology Of Hard Rock Gold Deposits
Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits. Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal. Gold has been the most highly esteemed and sought after precious commodity
Gold Dredge
Original gold dredging began in the very early 1900’s, mainly to harvest gravels and sands for gold in previously worked placer gold fields. Some of these gold fields are the California ones of the Sierra Nevada 1849 gold rush, the Yukon one of the Klondike area near Dawson City and Atlin, BC. These gold dredges typically harvested the sand and
Metal Detector Prospecting -Can you find GOLD
Metal detectors are used by recreational and professional gold prospectors. The term electronic prospecting is used in the literature to denote the use of metal detectors to find gold. Typically these metal detectors are used to discover placer deposits and isolated gold nuggets and flakes that are placer in origin. Metal detectors detect metals in the ground by transmitting an
Stocks of Undervalued Mining Companies
Here is a List of Undervalued Mining Companies and their Stocks organized by relative valuations. scotiabank.com
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 here plotted versus the P/NAV
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 starts with in-plant physical measurement
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, P80 grind size, pH and

Compare X-Ray to Laboratory Analysis-Measurement Reliability XRF-AA Comparison
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 a test on a lab
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 defined as an accumulation of
