Metallurgical facilities' penalties may be significant. For example, at the Samatosum copper-silver-gold mine in British Columbia, Canada, the mill produced copper concentrates that contained so much arsenic and antimony that the NSRs of the ore were reduced by up to 50% (Goldie 2022).. Because of its high arsenic content, the Armstrong …
Preparing a mine design involves three key items: ore body, mine plan, and infrastructure. The designer starts on the inside and designs outwards: The ore body (provided by nature and interpreted by geologists) is the basis for the mine plan (the mining method, recovery sequence, and productive capacity). The mine plan is supported by the …
