Calculate the Size of RainWater Storage System

french drain

One of the most important elements of designing a proper drainage system is determining how much rainwater is falling on your property and what to do with this volume of water. Here is a list of a few things that you will need: Paper A pen or pencil A tape measure A calculator. Now that […]

Geometallurgy Course & Geometallurgical Modelling

define kriging

Basic Geometallurgy Short Course for mineral processing applications   Geometallurgy and grinding It is often desirable to be able to load ore hardness information into the mine block model. Allows the mining engineers to better schedule ore delivery to the plant, and to run more sophisticated net present value calculations against ore blocks. Requires hundreds of samples from […]

Metallurgists Need Statistics

metallurgists-need-statistics

Metallurgists Need Statistics like Pharmaceutical Researchers need Chemistry.  See, pharmaceutical manufacturers conduct clinical trials in which new medicines are tested on volunteers to evaluate efficacy and safety. These trials are conducted according to strict statistical protocols that are internationally mandated by government regulation. Why? Because experience has shown that statistically designed trials give the best […]

Mineral Composition and Fragmentation

flotation sample

The metallurgical response of minerals during the flotation process are dependent upon two factors: The fragmentation of the minerals from each other during the grinding stage establishes the limits to process metallurgy The relative abundance of the different minerals in the ore sample dictates the complexity of the flowsheet design.   Here we discus the mineral […]

Flotation Process Development and Assessment

ore-grade

At a mining operation, a project was designed and implemented to develop a process for controlling lead recovery in the flotation plant. The metallurgical program consisted of two parts: A survey of the current plant process streams was conducted first to assess the performance characteristics of the existing flowsheet and equipment. A comprehensive program of laboratory scale […]

Mill Critical Speed Calculation

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of […]

Estimate Mill Steel OR Rock Charge Volume

This is a 2nd Method for estimation or measuring the steel charge volume inside a mill. If dealing with a full SAG/AG mill, this will give you the rock load%.  If you can count liners, you’ll have your answer. The 1st method uses similar parameters.
