Metallurgical Accounting Formulas
Have you been looking for a quick way how to calculate your flotation circuit’s metal recovery? You have no concentrate weights all you have are metal assays. Here are the assay based recovery formulas you can use for your metallurgical accounting. Using these formulas, the Metallurgical/Metallurgy performance of the concentration plant or of a particular mill […]
SAG Mill Ball Size Evaluator | Evaluation Factors | Calculate Diameter
Lets calculate/select/pick a new ball for your SAG mill. Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a “small” circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls […]
Mining technology firm creates new system to process platinum
The mineral processing plant manufacturer Appropriate Process Technologies (APT) is currently changing its strategy to target platinum miners, in Zimbabwe. The company is designing a new modular platinum gravity recovery system that can be used to process primary ores. The firm’s chief executive, Kevin Peacocke, said in a statement that: We are focusing more on designing and incorporating […]
Calculate Recoveries with 2 or 3 Product Formulas
Here is the formula you need to calculate Metal Recoveries using Assays only. You have two products/concentrates. This will save you time in your metallurgy accounting calculations. Some call the same formula the two (2) product other the three (3) product formula. Frequently, a concentrator will mill a complex ore requiring the production of two separate […]

Flotation Reagent Metering Pumps
I recently did a reagent plant trial and worked with a pretty nice flotation reagent metering pumps. The pump is supplied by https://www.pmps.co.za This portable reagent supply unit is a mechanical diaphragm metering pump. As see on https://www.pmps.co.za/obl-mechanical-diaphragm-dosing-pump They even had “Water Driven Pumps” Other pumps I never worked with include https://www.awe-ltd.co.uk/products/dosing_pumps_electronic.html and https://www.lutzjescoamerica.com/index.php?id=1645 Also https://www.911metallurgist.com/mibc-frother-pump
