Title:
SORTING METHOD FOR VEINLET-DISSEMINATED PARAGENIC ORE OF WOLFRAMITE AND SCHEELITE
Document Type and Number:
WIPO Patent Application WO/2024/082415
Kind Code:
A1
Abstract:
The present invention provides a sorting method for veinlet-disseminated paragenic ore of wolframite and scheelite, which belongs to the technical field of ore dressing. In the present invention, a large amount of tailings are first discarded by means of a pre-selection and waste-ore-discarding operation, such that the amount of ore entering a subsequent ore grinding operation is reduced; and then the flotation of a sulfide ore and a further sorting treatment are performed, so as to achieve the recovery of a molybdenum concentrate, a copper concentrate and a tungsten concentrate. By using the method provided in the present invention for sorting the veinlet-disseminated paragenic ore of wolframite and scheelite, the development and utilization cost is low, and the economic benefit is high. The results of the embodiments show that when veinlet-disseminated paragenic ore of wolframite and scheelite with the grades of WO3, Mo and Cu being 0.17%, 0.011% and 0.126% respectively is subjected to sorting in the present invention, the waste-ore-discarding rate of a combined pre-selection and waste-ore-discarding operation is 52.67%, the grade of WO3 in the finally obtained tungsten concentrate is larger than 30%, and the recovery rate is close to 60%.
