Commissioning and Disinfecting Copper Plumbing Systems

Once a copper plumbing system has been installed, the system should be flushed and commissioned for service. While there are no special requirements for commissioning and disinfecting a copper system, there are precautions that should be taken to ensure the commissioning and disinfection procedure do not damage the system.


The source of the additional copper needed to supply this market may be different, however, than the recent past. Over the last 15 years, there has been a substantial expansion of mines using heap leaching methods for whole ore, coupled with SXEW, which has supplied copper metal to the market without the need for smelting. This

of the chloride/chlorine lies in the handling. Thus, it is important to select an effective substitute for chlorine. For extraction of gold from the refractory ores in which gold is surrounded by sulfide minerals, oxidative pretreatment of the ore is essential to oxidize the sulfides and expose gold.

Copper Wikipedia

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.

Elevated Magmatic Sulfur and Chlorine Contents in Ore

Although the process that caused the increase in sulfur and chlorine is not clear, reverse zoning seen in plagioclase phenocrysts from the P2 porphyry, and the occurrence of more mafic compositions in P2L, suggest that recharge of the deeper magma chamber by a relatively SClrich mafic magma may have triggered the oreforming hydrothermal event.
