Notes from the ore, the lab and the site.
Written by the team that runs the testwork, draws the flowsheets and operates the plants. Every figure traces to our project record or a named external source.

All notes
Ore Dressing Process: From Run-of-Mine Ore to ConcentrateThe full ore dressing chain, crushing to tailings, with the decision each stage owns and the warning signs of a wrong route.
Metallurgical Testwork: From Ore Sample to Plant DesignThe testwork stage chain, the design question each stage answers, and three programmes from the Xinhai archive.
Mineral Processing Flowsheet: From Testwork to DesignHow test data becomes a defensible flowsheet, which circuit shapes suit which ores, and what a wrong diagram costs after construction.
Iron Ore Beneficiation Plant Cost: What Actually Drives ItThe six drivers behind iron ore beneficiation plant cost, and how to estimate each one before committing capital.
Tailings Storage Facility: TSF Design and ManagementWhat a TSF is, why it concentrates so much long-term mine risk, the four design decisions that matter, and where GISTM fits.
Placer Mining: How Alluvial Gold Is Found and RecoveredHow placer deposits form, how they're mined wet and dry, and why gold particle size — not equipment brand — sets the recovery ceiling.
Mineral Processing Companies: How to Evaluate a ShortlistFive checks for choosing a mineral processing partner, plus a frank shortlist of international and Chinese firms — including where Xinhai fits.
Mineral Processing Plant Commissioning: Stage by StageThe five-stage commissioning chain, why design recovery and first-year recovery diverge, and the three things owners should track.
