Process flowsheets, how equipment works and how to adjust it, and the steps to build a plant — practical notes from process design and commissioning.
From ore sampling and testwork, process design and equipment sizing to site, water and power, permits, installation, commissioning and training — the main steps in building a small processing plant, and the common pitfalls.
Read article →A shaking table separates fine minerals by density using asymmetric reciprocating motion and a cross-flow of water. This guide explains how it works and how it is built, gives typical ranges for stroke, speed, deck slope, wash water, feed density and feed rate, and sets out a step-by-step adjustment method and a troubleshooting table.
Read article →Cassiterite is heavy but brittle and easily overground, so tin is recovered mainly by gravity. This guide covers the typical flowsheet for alluvial and hard-rock tin: stage grinding, hydraulic classification, jigs, spirals, sized shaking-table circuits, slime treatment, and flotation and magnetic cleaning to remove sulfides and iron minerals.
Read article →Placer gold is mostly free gold that needs no grinding — the job is to wash it out and hold on to it. This guide walks through washing and screening, desliming, roughing, cleaning and final recovery, plus water recycling and when to choose mobile equipment.
