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.
