making brass. Brass is a copper-zinc alloy. Alloying produces a metal harder than either copper or zinc individually. Bronze is another copper alloy, but with tin. coinage. In many countries, as well as the more obvious copper-colored coins, "silver" coins are also copper alloys this time with nickel; these are known as cupronickel alloys.

Leaching and recovery of zinc and copper from brass slag

The analysis of the residue (slag sample after leaching process) indicated that it contained only quartz (SiO 2) as the main constituent. 4. Conclusions. Leaching of brass slag to recover zinc and copper in sulfuric acid solutions was studied. It was found that the zinc extraction was fast and increased with sulfuric acid concentration.

2020-06-07· Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 °C, 1,650 to 1,720 °F, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass

Chemistry of Copper Chemistry LibreTexts

Early metalsmiths as far back as 3000 BC learned to combine copper with other metals to produce more durable alloys. Brass (copper and zinc) and bronze (copper and tin) are two examples. The symbol and name for copper are from the Latin cuprum, which literally means "from the island of Cyprus", an early source of copper ore.
