Gold Flotation Production Line-JIEMA

【Process Introduction】
Flotation is the most common method for processing rock gold ores, especially sulfide-bearing ores with high floatability. It efficiently enriches gold in sulfide minerals, while tailings can be directly discarded, resulting in low cost. About 80% of rock gold ores in China use this process.

【Application Fields】
Suitable for fine-grained, highly floatable sulfide-bearing quartz vein gold ores, polymetallic gold sulfide ores, and carbonaceous (graphite) ores.

【Process Flow】
Typically a single-stage grinding-flotation circuit is used. For ores with uneven dissemination, stage grinding and flotation can be applied.

Grinding Fineness: Gold in sulfides requires only sulfide liberation; gold intergrown with gangue requires full liberation. Fineness is determined by testing.

Pulp Density: Coarse, high-density particles → thicker pulp; fine, low-density particles → thinner pulp. Roughing uses thicker pulp for higher recovery; cleaning uses thinner pulp for better concentrate grade.

【Other Conditions】
Include pulp density, reagent dosage, aeration rate, flotation time, etc., determined by testing. Common reagents: collectors, activators, and frothers.
