While copper is unique as a metal, its production also shares aspects in common with other metals:
- New mining projects are subject to extensive consultations with local communities and negotiations with local and national governments.
- New mines need a long time to start up: depending on the the regulatory environment and how stakeholder consultations evolve, start-up times vary between 5 and 25 years. The average start-up time for a new mine is 16 years, according to IEA.
- Ore grades are declining.
- Mining costs are going up - e.g. a hauling vehicle in Chiquicamata needs 3 hours from the bottom of the pit to the mill. With changing market conditions, a mining project is a continual business decision. Mining projects are capital-intensive. Mining projects also have high operational costs (labour, energy, water).
- Mining is risky business, and risk lead to a higher cost of capital.
- For underground mining, the management of heat, humidity and water in a space-constrained environment is a constant struggle.
- Most mines need some level of concentration of materials, and in any case, management of both hazardous & non-hazardous waste.
- All mining is looking for reuse of its waste rock in building construction and civil engineering. The circularity potential from mining is not yet fully understood and leaves untapped potential.
- Water use and discharge - in some cases, risk of pollution of nearby rivers or lakes.
- Besides water, mining requires energy and explosives.
- During a mining operation, on-site loss of biodiversity is unavoidable. There are mitigation, offsetting and other possibilities to restore biodiversity and achieve no-net-loss.
- Mining changes landscapes in an often irreversible manner. A mining project includes a rehabilitation plan to repurpose an area after a mining project has been completed. Some very creative uses for mines have been found after closure [2].
- Location: much metal mining takes place in remote locations that are far away from where mining products are used.
