Evaluating Copper Flotation Cleaner Circuit Grade – Recovery Results
To facilitate the presentation of the modal data, the cleaner circuit of this case concentrator was separated into three operations. The first cleaner circuit, which includes the cleaner-scavenger bank is discussed first, this is followed by a discussion of the operation of the column cleaner circuit. Finally, an analysis of the overall cleaner circuit operation is […]
Mill Operating Work Index Calculator (Ball/Rod/SAG)
Calculate a Mill’s Operating Work Index
Use this online formula to calculate a Ball Mill, Rod Mill or SAG Mill Operating Work Index. Based on Fred Bond’s work you can estimate the energy used into your grinding circuit. This is the most accurate and informative method, but much of the data necessary for its application is not yet available. A) Total […]
Mass Balancing Extended to Machine Learning
The methodology MIDAS Tech International has been developing has migrated from mass balancing to information theory to machine learning. It appears these methods are the only ones available that allow unit processes to be modelled in detail; entirely from the data. This is ideal for a simulation system that can be used for both data-driven […]

Circulating Load Calculation Formula
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known […]

How to Select a Rainwater Catch Basin
You need to know how much water will be draining to your catch basin in order to select the right catch basin for your project. Catch basins are an effective way to collect surface water that is draining to one specific area like a low spot in the yard or below a rain gutter downspout. […]
404 Basic Mineral Processing Terms
ABC: Assay Based Controls are changes made to regulatory setpoints that are biased on the level or changes in the level of the valuable metal being recovered. ABC Circuit: A two-stage grinding circuit composed of an autogenous mill, a ball mill and a crusher. Abrasion: Wearing away by rubbing or friction. Acicular: Having the […]
