Tom Revy, CEO of emerging producer Hawsons Iron (ASX:HIO), says direct reduced iron (DRI) plants prefer iron ore pellets with an iron content of at least 67%, with lower concentrations of impurities and acid gangue (silica, alumina and phosphorus).. Revy says this improves the economics of operating the facility and allows the resulting product to be charged …

MINING: Cadmium-containing ores are extracted using both surface and underground mining techniques. In surface mining, also known as open-pit mining, cadmium ore is excavated from open pits. These pits are created by drilling into the step walls of the mine, which are strategically designed for extensive excavation.
