1. Concentrated carbonate of zinc is converted to its oxide by calcination. In this process, zinc carbonate ore is strongly heated in the absence of air to produce zinc oxide and carbon dioxide gas. 2. Zinc oxide is then reduced by coke (carbon). When zinc oxide is heated with coke, carbon acts as a reducing agent and reduces zinc oxide to zinc.

In this stage of the process, gold is oxidised. Zinc dust is then added to the cyanide solution. The zinc then takes the place of the gold, so that the gold is precipitated out of the solution. This process is shown in Figure 14.4. Figure 14.4: Flow diagram showing how gold is processed. Characteristics and uses of gold (ESBRN)

However, in some cases, when removal time rolls around, you'll find that a chunk of the zinc (after considerable wastage) has simply fallen off, separating itself from both the plug and whatever zinc remains attached to it. Moreover, the chunk is simply lurking down there in the dark, preventing you from installing a new zinc!

Extraction of Zinc Zinc Mining. The most commonly available ore used in the extraction of zinc is called zinc blende also known as zinc sulphide (ZnS). Historically extraction of zinc has been more difficult than the extraction of other metals because, at temperatures where metals such as iron typically begin to melt, zinc is a gas.
