Antimicrobial copper-alloy touch surfaces Antimicrobial copper-alloy touch surfaces Antimicrobial copper-alloy touch surfaces can prevent frequently touched surfaces from serving as reservoirs for the spread of pathogenic microbes. This is especially true in healthcare facilities, where harmful viruses, bacteria, and fungi colonize and persist on doorknobs, push plates, railings, tray tables, tap (faucet) handles, IV poles, HVAC systems, and other equipment. These microbes can often survive on surfaces for surprisingly long periods of time (sometimes more than 30 days). The surfaces of copper and its alloys, such as brass and bronze, are antimicrobial. They have an inherent ability to kill a wide range of harmful
Sundown Tin and Copper Mine furnace were in working order. 30 tons of arsenic and 5.4 tons of copper were produced in 1922, and 200 tons of arsenic in 1923. In 1924 the furnace and part of the mill was leased by Arsenic Limited to O.C Roberts Limited, who remodelled the furnace to treat high-grade ore, as a result of the Prickly Pear Land Commission letting a 12-month contract for the supply of Roberts Improved Pear Poison, which was manufactured at Wallangarra. The ore was to come form the nearby Beecroft Mine. The arsenic works ceased operation in 1925, and tin does not seem to
