Metal ore mining in Europe

In Sweden, Lundin Mining owns the Zinkgruvan zinc-lead-copper underground mine, where the planned 2018 zinc output is around 79 kt. Terrafine owns a nickel-zinc mine in Sotkamo in Finland where a total of 31.5 Mta of ore were mined in 2017. The ore is subjected to a primary and secondary bioleaching process.

Lead Zinc Mining Solution

1. Mixed flotation-lead zinc separation Process advantages: The flotation process performs two mixed flotation of lead and zinc under weak alkaline conditions, and separates lead and zinc under weak acid conditions. The process of mixing lead and zinc twice can discard the tailings at one time and reduce metal loss. In the lead-zinc ore ...
