how is copper ore separated from the host rock
Bingham Canyon (Kennecott) Copper Mine ~ Mining Geology
Apr 27, 2015· Tiny grains of ore minerals, mostly copper and iron sulfides, are scattered within what is called "host rock." Because there is far more host rock than there are minerals, it is known as a lowgrade ore deposit. Because this is a lowgrade deposit, a ton of ore contains only about pounds of copper.

elaborate techniques to break down the sulphide rock so that the rest of the gold, copper and silver can be liberated. Fortunately, we can concentrate the sulphides using a process called 'flotation' where chemicals are added to the finely ground rock, causing the ore to float and thus separate from the waste rock.

Host Rock an overview | ScienceDirect Topics
The host rocks are sedimentary rocks of the Marquette–Baraga Supergroup comprising slates, iron formations, quartzites, and older cherty carbonate. The main Bovine intrusion is composed of a large gabbroic inner core with two thin rims in succession. The inner core (upper unit) is composed of finegrained gabbro with thickness varying between 30 and 150 m.
