1. PYNPUNT GEDREWE OPENING

Skaal goud herstel bedrywighede na 500 Tph bied duidelike ingenieurs- en finansiële uitdagings. Aanlegbestuurders en ingenieurskontrakteurs kom dikwels in die gesig:
Deurset-bottelnekke: Inefficient scrubbing and screening can cap processing capacity below 500 Tph, leaving valuable material unprocessed and limiting ROI on your deposit.
Hoë Water & Kragverbruik: Traditional washing plants can require excessive water recirculation and highhorsepower drives, directly escalating operational costs and environmental footprint.
ClayBearing Material Handling: Sticky clays and agglomerates can blind screens, reduce classification efficiency, and cause significant downtime for manual cleaning.
Inkonsekwente herstelkoerse: Variable feed material can lead to gold losses in fines or to inadequate liberation of gold from gangue, impacting overall plant yield.
Vinnige Dra & Onderhoudskoste: The abrasive nature of alluvial or hard rock feed can lead to premature failure of critical components, resulting in unplanned stoppages and high parts replacement costs.

Is your operation achieving maximum payable gold recovery at a true 500tonperhour rate? Are you managing water and energy costs effectively while minimizing maintenance downtime?

2. PRODUK OORSIG

A 500 Tph Gold Mining Washing Plant is a highcapacity, modulêre verwerkingstelsel ontwerp vir die primêre skrop, vertoning, en swaartekragkonsentrasie van alluviale of eluviale afsettings, or the preconcentration of hard rock mill feed. Its core function is to liberate gold particles from waste material (gangue) and efficiently separate them by size and specific gravity.

Operasionele werkvloei:
1. Voer & Primêre skrop: Runofmyne (ROM) material is fed into a robust scrubber (trommel or rotary) where intense agitation breaks down clays, dissolves cemented aggregates, and liberates gold.
2. Grootte & Klassifikasie: The scrubbed ore passes over vibrating screens or within the trommel itself to separate material into distinct size fractions (bv., +10mm oversize waste, 10mm+2mm gravels, 2mm sands).
3. Swaartekrag konsentrasie: The goldbearing sand fraction is routed to a series of highcapacity gravity concentrators (soos sentrifugale konsentrators of sluise) to recover free gold particles.
4. Uitskotbestuur & Water Herwinning: Waste streams are conveyed away, while process water is sent to a settling system for clarification and recirculation.

Toepassingsomvang & Beperkings:
This plant is engineered for largescale placer operations, alluvial projects, or as a primary wash plant for certain weathered deposits. Its effectiveness is highest on freemilling gold where liberation occurs through physical scrubbing. It is not a substitute for chemical leaching (CIL/CIP) plants required for refractory ores.

Eluvial Gold Project in South America

Uitdaging: Recovering fine flour gold from highly weathered saprolitic ore required maximum scrubbing efficiency while minimizing water usage due to remote location constraints.
Oplossing: A twostage washing plant was deployed using an initial scrubber followed by a log washer for stubborn clays before classification into multiple gravity circuits tailored for fine gold recovery.
Resultate: Field data shows overall water consumption was reduced by $28\% against the project's baseline target while achieving targeted fine gold recovery rates above $95\%$ in the gravity circuit alone.
