What are environmental regulations on mining activities

The framework for mining regulation is primarily based on federal laws dating back to the late 1960s. In many cases, these regulatory responsibilities have been delegated to state agencies, which have in turn developed their own sets of environmental laws, regulations

explanation. "Run-of-mine" ore is a mix of valuable minerals and worthless rock in which each ingredient is priced separately. Run- of-mine ore is treated in the dressing plant and processed into different concentrates. Where the ore contains more than one metal of value, separate concentrates of, for example, copper, zinc, and lead are produced.
