Abstract

The invention discloses a machining method for comprehensive utilization of waste rock of the Hainan Shilu iron mine. According to the machining method, the waste rock is evenly fed into a first screening machine through a feeding machine, and the first screening machine screens the waste rock into three types including large rock, medium-sized rock and small rock; minerals and large stone are sorted out from the large rock through a mineral sorting machine; minerals and medium-sized stone are sorted out from the medium-sized rock through a mineral sorting machine; the small rock is broken through a breaker and then conveyed into a mineral sorting machine, and minerals and small stone are sorted out; and the small stone and powder are fed into a ball mill to be ground, the ground small stone and the ground powder are then conveyed into a second screening machine, and then gravel and building sand of three specifications including the large size, the medium size and the small size are screened out. By the adoption of the machining method for comprehensive utilization of the waste rock of the Hainan Shilu iron mine, the waste rock is recycled to be manufactured into products having the economic value, so that the economic benefit is improved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of recovery and reuse of mine waste, in particular to a processing method for comprehensive utilization of waste rock of Shilu Iron Mine in Hainan. Background technique [0002] The Shilu Iron Mine in Changjiang County, Hainan Province is a famous large-scale iron-rich deposit in my country, with a total proven reserve of 466 million tons. The mining of Shilu Iron Mine in Hainan lasted 70 years. The total amount of stripped rock is hundreds of millions of tons. A huge dump was formed. At present, it has been sleeping for many years and occupies a large amount of land. Some locations are close to the county seat. In the dry season, strong winds blow and dust will seriously affect the surrounding environment. During the rainy season, debris flows and sediment flows are likely to form in some areas after being washed by heavy rains. Huge mudslides will block irrigation canals, bury fertile fields, pollute w...
