Introduction Bagacay Mines in Western Samar ranks first for remediation out of the seven priority abandoned mine sites identified by the Mines and Geosciences Bureau . Environmental problems in Bagacay Mines: Formation of Acid Mine Drainage Pollutants from the mining site were blamed for the death of Taft River.
chemical separation techniques such as gravity concentration, magnetic separation, electrostatic separation, flotation, solvent extraction, electrowinning, leaching, precipitation, and amalgamation . Wastes from these processes include waste rock dumps, tailings, heap leach materials
The Bagacay Copper Mine is a surface and underground mining operation. Initial production took place in 1956. Mine operations consist of surface workings. There is one known shaft. The mining method is open pit. Information from 1979 described the ore body as having an unknown shape 2,500 meters long, 1,000 meters wide, and 50 meters thick.
Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock. The unwanted rock is called waste rock. The choc chips are separated from the rest of the biscuit, just as minerals are extracted from the rock.
o Membrane separation Manufactured SteamMethane Reforming Most common method of manufacturing hydrogen 90 95 vol% typical purity Gasification / Partial Oxidation Produce synthesis gas Hydrogen recovery o Pressure swing adsorption o Membrane separation More expensive than steam
of which will be explored later in this paper. The process of producing this CO 2 stream is referred to as separation and capture, which encompasses all operations that take place at the power plant site, including compression. For ease of transport, CO 2 is generally compressed to the order of 100 atm 2.
