Free Milling Gold Ores
Many problems on free milling gold ores have been solved by the 911MPE Testing Laboratory. One free milling gold ore received for testing the application of the Mineral Jig in the Ball Mill Classifier circuit gave the following results: Head Ore, 0.65 oz. Gold per ton (Assayed) 0.643 oz. Gold per ton (Calculated) Amalgam from Amalgamation […]

The concept of project value tracking and its application in project planning at Anglo Platinum Flotation process optimization through frequent in-line grade measurement as an alternative to sampling surveys that deliver outdated results Case studies of simultaneous mining and mineral processing optimization applied to platinum and nickel operations Optimizing concentrate allocation to Anglo Platinum smelters […]
How to Prevent Crusher Choking
We all understand how choke feeding a crusher makes for good operation and product size but operators need to also know How to Prevent and avoid that same Crusher from Choking. It is apparent that although the distance between successive horizontal planes increases gradually as these planes move downward (due to increased throw of the […]

The Density of Liquids and Solids
Density data may be used for obtaining relationships between density, chemical composition, thermal and mechanical treatments of materials, etc. This circular defines density and specific gravity, describes 11 methods (hydrostatic weighing, pycnometer, flotation, hydrometer, falling drop, balanced column, Boyle’s law. electromagnetic, elastic helix, ice calorimeter, and volumetric) for determinations of the densities of solids and […]

How to Become a Metallurgist
YES! Become a Great METALLURGIST Going from “Being”, to Good, to GREAT! Some say it is a matter of doing certain things. Others say it is a matter of doing things in a certain way. Here a very detailed list of specific skills under the heading “Mineral Processing Basics” that can be further categorised into the following […]
Flotation Cyanidation CIL Tailings
This simple process flowsheet allows for Flotation Cyanidation Tailings in cases where ore bodies at depth have become more refractory and dotation ahead of cyanidation would call for major and expensive mill alterations, the sulphide minerals containing the undissolved precious metals can be recovered by flotation and shipped to the smelter. In some cases it […]

Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive […]
