1. ABERTURA ACIONADA POR PAINPOINT

Os custos operacionais crescentes e o tempo de inatividade imprevisível estão corroendo as margens do seu projeto de mineração de ouro? The efficiency of your recovery operation hinges on the reliability and precision of your core extraction and processing equipment. Common challenges with suboptimal machinery include:

Altos gastos operacionais: Inefficient equipment consumes excessive power and water, while poor recovery rates leave valuable micron gold in the tailings, impactando diretamente a receita.
Tempo de inatividade excessivo para manutenção: Frequent mechanical failures in harsh mining environments lead to unscheduled stoppages, halting entire processing lines and delaying production targets.
Inconsistent Recovery Performance: Variable feed grades and particle sizes can overwhelm static systems, causing gold losses and requiring constant manual adjustment from your plant operators.
High Chemical Consumption: Nonoptimized systems often overconsume reagents like cyanide or flotation chemicals, unnecessarily increasing both cost and environmental management complexity.

Is your current setup delivering the consistent tonnageperhour and recovery percentage your feasibility study promised? The selection of engineered equipamento de mineração de ouro is a primary determinant of your site's longterm profitability.

2. VISÃO GERAL DO PRODUTO: MODULAR GRAVITY CONCENTRATION & CYANIDATION PLANT

This product line encompasses a suite of integrated equipamento de mineração de ouro designed for primary and secondary alluvial/hard rock operations. The system focuses on maximizing recovery rate (%), minimizing operational cost ($/tonelada), and ensuring operational simplicity.

Fluxo de Trabalho Operacional:
1. Britagem Primária & Milling: Feed material is reduced to a target liberation size via jaw crushers and ball mills.
2. Gravity PreConcentration: A centrifugal concentrator (por exemplo, Tipo Knelson ou Falcon) recovers coarse free gold immediately, reducing downstream load.
3. Lixiviação & Adsorção: The gravity tailings report to an agitated leach tank circuit where gold is dissolved. The pregnant solution then flows through a series of carbon adsorption columns (CIP/CIL).
4. Eletrovimentação & Fundição: O carbono carregado é tratado em uma coluna de eluição; the highgrade eluate is processed in an electrowinning cell to produce cathode sludge, which is then smelted into doré bars.

Escopo de aplicação & Limitações:
Escopo: Ideal for mediumscale operations processing 50 500 toneladas por dia (TPD). Effective for both freemilling ores and some refractory ores with pretreatment. Suitable for fixed plant or modular deployment.
Limitações: Not a standalone solution for highly refractory ores requiring biooxidation or pressure oxidation. Feed particle size must be controlled within design parameters for optimal recovery.
