Pretreatment system for recovering valuable components from low-grade gold-silver-iron oxidized ore

The utility model relates to a pretreatment system for recovering valuable components from low-grade gold-silver-iron oxidized ore. Comprising a first vibrating screen, a second vibrating screen, a jaw crusher, a photoelectric intelligent sorting machine, a high-pressure roller mill, a high-pressure water vibrating screen, a first pump pool, a first ore pulp and dense medium cyclone sorting machine, a second pump pool, a second ore pulp pump and a hydrocyclone sorting machine. According to the distribution characteristics of gold, silver and iron in the low-grade gold-silver-iron oxidized ore and the natural binding force property of multi-mineral aggregate ore blocks, a group of sequential treatment systems is researched and developed, proper equipment specifications are configured, valuable components in the low-grade gold-silver-iron oxidized ore are effectively recycled, the recycling rate is high, and the cost is low. And about 50% of discarded coarse-grained waste rocks can be used as high-quality build
