Simple Mineral Dressing Lines for Gold, Copper & Iron Ore

In African and South American metal mining markets (such as Mali, Congo DR, Chile and Zimbabwe), small and medium-sized mines account for a large proportion, with the characteristics of limited investment, simple processing needs and insufficient professional technical personnel. Simple mineral dressing lines for gold ore, copper ore and iron ore have the advantages of simple process, easy operation, low investment and high recovery rate, which are perfectly suitable for these small and medium-sized metal mines.

### Core Design Concept & Applicable Scenarios

The core design concept is "simplify the process, ensure efficiency, reduce cost and adapt to localization". It is mainly applicable to small and medium-sized mines with medium to high ore grade, simple mineral composition and no complex separation requirements. It covers three types of mineral dressing lines: gold ore, copper ore and iron ore, and can be customized according to ore characteristics and production capacity (50-300TPH).

### Process Flow & Equipment Configuration (200TPH Iron Ore Example)

The whole line is divided into three stages: crushing, screening and simple dressing, with a total length of 50-80 meters, compact layout and no need for complex civil engineering, which can be put into operation in 15-20 days.

1. Crushing Stage: Adopt "primary crushing + secondary crushing" process. Primary crushing: Jaw crusher (model C6X130, feeding size ≤500mm, processing capacity 180-250TPH), crushing large iron ore into small particles of ≤100mm. Secondary crushing: Hydraulic cone crusher (model HP200, feeding size ≤145mm, processing capacity 81-250TPH), crushing materials into ≤20mm particles.

2. Screening Stage: Equipped with 2 sets of 3-layer high-efficiency vibrating screens, separating crushed materials into three grades: ≥20mm (return to secondary crushing), 10-20mm (coarse concentrate), 0-10mm (fine concentrate and tailings).

3. Simple Dressing Stage: Adopt gravity separation method (simple, low-cost and environment-friendly), equipped with spiral classifier and shaking table. The 0-10mm material enters the spiral classifier for desliming, then enters the shaking table for separation. The concentrate (iron grade ≥60%) is collected as finished product, and the tailings are used for road filling or building materials.

### Key Equipment Advantages

Jaw crushers have high crushing ratio and wear-resistant liners, suitable for crushing hard iron ore and copper ore, and are easy to operate for local workers without professional training. Hydraulic cone crushers have high efficiency and stable performance, can accurately control the particle size of crushed products, and the hydraulic system is easy to maintain. Gravity separation equipment has simple structure, no chemical reagents, environmental protection and pollution-free, and low energy consumption.

### Regional Adaptation & Case

For French-speaking African countries (Mali, Congo DR, Guinea), French operation manuals, French-speaking technical guidance and on-site training are provided. For South American countries (Chile, Colombia), English operation manuals and remote technical support are provided, with spare parts reserved in local warehouses.

Case: 150TPH Gold Ore Simple Dressing Line in Mali - Located in Bamako, the line adopts jaw crusher + impact crusher + gravity separation equipment, with a gold recovery rate of ≥85%. Local workers can master operation skills after 3 days of training, and the daily output of gold concentrate reaches 50kg, bringing stable economic benefits.
