What Are the Uses of Graphite? | Sciencing

"Lead" pencil cores are made of a mixture of clay and graphite. Loosely cleaved graphite flakes mark the paper, and the clay acts as a binding material. The higher the graphite content of the core, the softer the pencil and the darker its trace. There is no lead in what are known as lead pencils.

Froth Flotation (Sulphide & Oxide)

Regarding to some comments, the best way to deal with naturally floating carbon is by pre-flotation. It should be mentioned that, the pre-flotation concentrate usually is discarded directly to tailings, however this stream contains significant amount of lead and zinc. How can we reduce lead and zinc loss to preflotation concentrate.

Zinc–carbon battery - Wikipedia

A zinc–carbon battery is a dry cell primary battery that delivers about 1.5 volts of direct current from the electrochemical reaction between zinc and manganese dioxide.A carbon rod collects the current from the manganese dioxide electrode, giving the name to the cell. A dry cell is usually made from zinc which serves as the anode with a negative electrical polarity, while the inert carbon ...
