Zinc is critical for the low-carbon economy. Here's why
The metal plays a critical role in enabling other green technologies too, like solar and wind. Zinc coatings protect solar panels and wind turbines and prevent rust. A 10MWh offshore wind turbine requires . 4 tonnes of zinc, while a 100MWh solar panel park—enough to supply 110,000 homes—requires 240 tonnes of zinc.

A Process Mineralogy Approach to the Flotation of Complex Lead–Zinc
Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a tool to …
