Zinc cannot only be a threat to cattle, but also to plant species. Plants often have a zinc uptake that their systems cannot handle, due to the accumulation of zinc in soils. On zincrich soils only a limited number of plants has a chance of survival. That is why there is not much plant diversity near zincdisposing factories.

Being a high temperature process the reaction kinetics are fast and this favours a low capital investment for the plant required. It looks as if the increase in annual revenue, net of operating costs, will be about the same as the capital investment for a furnace retrofitted to an existing mine and concentrator.

The increasing use of zinccontaining scrap for steel production has lead to a high zinc content in the electric arc furnace and converter flue dusts. The cost of disposing of this residue is high due to environmental restrictions. Various recycling processes have been developed for these dusts, but most never reached the pilot plant stage and many investigations were stopped because of ...

Zinc output lagged consumption by 296,000 tons in 2014, according to the International Lead and Zinc Study Group (de Sousa and Clarke, par. 7). This research suggests that either new zinc reserves must be discovered or the price of zinc must increase significantly to offset the cost of mining currently known, but less accessible, reserves.
