The ores of sulfide copper-nickel, copper-pyrite deposits, and ores of copper sandstones and slates are primarily pro-cessed abroad. The amount of copper in copper sand-stones and slates varies from 1 to 6%, in sulfide cop-per-nickel ores from 1.1 to 4.9%, in copper-pyrite ores from 0.1 to 3%, and in copper-porphyry ores from 0.4 to 1.2%.
