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? Os operadores comerciais enfrentam consistentemente desafios críticos que impactam diretamente a rentabilidade:

Altos gastos operacionais: Consumo excessivo de combustível, substituição frequente de componentes, e o alto uso de água no processamento criam estruturas de custos insustentáveis.
Tempo de inatividade não planejado: Equipment failure in remote locations leads to significant production halts, with repair logistics costing thousands per hour in lost recovery.
Baixas taxas de recuperação & Variabilidade de notas: Inefficient separation results in valuable fine gold loss to tailings, while inflexible equipment struggles with changing ore body characteristics.
Intensidade de Trabalho & Escassez de habilidades: Reliance on complex, manuallyadjusted systems increases labor costs and introduces human error, a critical issue in regions with scarce skilled technicians.
Ambiental & Pressão Regulatória: Inefficient water recycling and chemical use increase operational costs and regulatory compliance risks.

Is your operation equipped to lower your cost per ton, maximize recovery from complex ores, and ensure reliable uptime in demanding environments? The right equipment portfolio is a strategic investment, not just a capital purchase.

2. VISÃO GERAL DO PRODUTO: MODULAR GRAVITY CONCENTRATION & PROCESSING PLANTS

This product line encompasses modular, highcapacity gravity concentration systems designed for alluvial (colocador) e rocha dura (veio) primary and secondary gold recovery. Engineered for the commercialscale operation, these plants optimize the physical separation of gold from gangue material based on specific gravity differentials.

Fluxo de Trabalho Operacional:
1. Preparação de alimentação: Raw material is screened and classified to ensure optimal feed size for downstream concentration.
2. Concentração Primária: HighG force centrifugal concentrators continuously separate heavy minerals (ouro) from lighter materials.
3. Middlings & Manuseio de Rejeitos: Efficient slurry routing ensures maximum recovery while minimizing water consumption.
4. Concentrate Upgrading: The produced heavy mineral concentrate is easily discharged for further upgrading via shaking tables or selective batch concentrators.
5. Gestão da Água: Integrated water recirculation systems are standard, drastically reducing fresh water intake and settling pond requirements.

Escopo de aplicação: Ideal for processing alluvial deposits, materiais eluviais, and milled hard rock ores where free gold is present. Serves as a primary recovery unit or a scavenger for ball mill/grinding circuit discharges.

Limitações: Not a chemical leaching system. Recovery efficiency is inherently tied to the liberation size of the gold particles. For refractory ores where gold is locked within sulfide minerals, this system functions as a preconcentration stage ahead of leaching circuits.

Operação de mineração aluvial de placer – África Ocidental

Desafio:Uma operação de placer em grande escala estava perdendo ouro fino significativo (<100 malha) to tailings using traditional sluices due to fluctuating feed grades and high clay content.Solution:The deployment of two modular gravity plants as primary concentrators after scrubber screens.The automated controls adjusted fluidization parameters as clay content varied throughout the pay streak.Resultados: Plant recovery increased from an estimated 65% to a measured 92%. The reduced water demand allowed operation during seasonal dry periods.The payback period on capital expenditure was achieved within eight months based on incremental recovered ounces alone.
