LCA was performed on the leadzinc ore mining and beneficiation. Processing plant can bring the more serious pollution than other subsystems. Pollution from tailings and chemical production should be controlled as a priority. Secondary metal production and clean energy need to be developed in China.

Zinc and Lead

We mine and process zinc and lead ores in the key mining regions of Australia, South America, Kazakhstan and Canada. And, we smelt and refine zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan. We also source and recycle zinc and lead materials in Europe and North America.
