Too Much Zinc Causes a Copper Deficiency
This can cause a copper deficiency, which is not what you want. So, be careful with those zinc supplements. Taking too much can lead to short-term side effects like nausea and vomiting (aka metal fume fever) and more serious long-term effects. It can mess with your hemoglobin production and leave you feeling tired.

What are by-products of copper production? – Knowledge …
For some of these elements, copper mining complements the production infrastructure of the by-product (e.g. gold, silver, lead, zinc or molybdenum). Other minor metals have limited or no own production infrastructure (e.g. selenium or tellurium). Hereby a list of commonly found by-metals in copper mining with a few of their applications:

Table of Electrical Resistivity and Conductivity
This table presents the electrical resistivity and electrical conductivity of several materials. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity, the more readily the material permits the flow of electric charge.

A zinc sulfate solution is floated on top of the copper sulfate solution; then a zinc electrode is placed in the zinc sulfate solution. Connecting the copper electrode to the zinc electrode allows an electric current to flow. This is an example of a cell without a salt bridge, and ions may flow across the interface between the two solutions.
