Abstract:

Ta Phoi Copper Joint Stock Company - Vinacomin officially been accepted and put into production from November 2019 with a closed technology process from mining to mineral processing. At present, the company has been entering the stage of stabilizing production in all fields and on the path of sustainable development. With the Company’s 5-year production plan (2021-2025), the capacity of raw copper ore is 1,000,000 tons/year, the average content of 0.8% Cu, the product obtained is ≥ 32,000 tons of concentrate. Copper content 23%, actual product requirements to achieve higher than design is a big difficulty. In order to well implement the above plan, the Company determines that mineral processing is the most important stage in production in order to improve output, reduce the cost of producing concentrates, and avoid wasting resources. This paper presents some research results of schematic flotation to propose some technological solutions that can be put into application at Ta Phoi copper processin g plant - Lao Cai, and at the same time introduces an impro vement technological diagram of the plant. The purpose of technological solutions and equipment applied at Ta Phoi copper plant - Lao Cai is to obtain copper concentrate products with a content of 23% Cu, the recovery is over 91.5%.
