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. SMP designs simple mineral dressing lines for gold ore, copper ore and iron ore, which have the advantages of simple process, easy operation, low investment and high recovery rate, and are perfectly suitable for small and medium-sized metal mines in these regions.
### Core Design Concept & Applicable Scenarios
The core design concept of SMP simple mineral dressing line is "simplify the process, ensure efficiency, reduce cost and adapt to localization". It is mainly applicable to small and medium-sized mines with ore grade of medium to high, simple mineral composition and no complex separation requirements. It covers three types of mineral dressing lines: gold ore simple dressing line, copper ore simple dressing line and iron ore simple dressing line, and can be customized according to the ore characteristics and production capacity (50-300TPH).
### Process Flow & Equipment Configuration (Taking 200TPH Iron Ore Simple Dressing Line as an 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: SMP C6X jaw crusher (model C6X130, feeding size ≤500mm, processing capacity 180-250TPH), which is used to crush large iron ore into small particles of ≤100mm. Secondary crushing: SMP hydraulic cone crusher (model HP200, feeding size ≤145mm, processing capacity 81-250TPH), which crushes the material into ≤20mm particles, laying the foundation for subsequent screening and dressing.
2. Screening Stage: Equipped with 2 sets of high-efficiency vibrating screens (3 layers), which separate the crushed materials into three grades: ≥20mm (return to secondary crushing for reprocessing), 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, and 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, realizing resource reuse.
### Key Equipment Advantages for Metal Ore Dressing
1. C6X Jaw Crusher: High crushing ratio, wear-resistant liner, suitable for crushing hard iron ore and copper ore, and the operation is simple, which is convenient for operation by local workers without professional training.
2. Hydraulic Cone Crusher: High efficiency, stable performance, can accurately control the particle size of crushed products, and the hydraulic system is easy to maintain, reducing the later operation cost.
3. Gravity Separation Equipment: Simple structure, no chemical reagents, environmental protection and pollution-free, suitable for areas with strict environmental protection requirements; low energy consumption, reducing the power cost of mines.
### Regional Adaptation & Service Support
For French-speaking African countries (Mali, Congo DR, Guinea), SMP provides French operation manuals, French-speaking technical guidance and on-site training to solve the problem of language communication. For South American countries (Chile, Colombia), English operation manuals and remote technical support are provided, and spare parts are reserved in local warehouses to ensure timely supply.
Case: SMP 150TPH Gold Ore Simple Dressing Line in Mali - Located in Bamako, Mali, the line adopts jaw crusher + impact crusher + gravity separation equipment, with a gold recovery rate of ≥85%. The whole line is easy to operate, and local workers can master the operation skills after 3 days of training. The daily output of gold concentrate reaches 50kg, bringing stable economic benefits to the mine owner.
