Sizing an Equipment Grounding Conductor for a Tap ...
The equipment grounding conductor based on Table 250122 for the 50ampere range circuit is a No. 10 copper or No. 8 aluminum. The equipment grounding conductor for the 20ampere tap would also normally be sized in accordance with the 50ampere overcurrent protection device, or a No. 10 copper conductor equipment grounding conductor.
Ground Wire Size Calculator
The Ground Conductor Size Calculator will calculate the proper ground conductor size for grounding raceways and equipment based on ampere rating or setting of automatic overcurrent protection device in circuit ahead of equipment. This is based on NEC (NFPA 70®: National Electrical Code® (NEC®), 2014 Edition) Table
Copper extraction Wikipedia
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Equipment Grounding Conductor Performance | Electrical ...
An equipment grounding conductor (EGC) installed with a branch circuit or feeder circuit performs three important functions in the electrical safety system. EGCs provide a path that connects equipment to ground, thereby performing grounding functions. The EGC extends the ground connection to various points in the electrical system because it is generally installed with feeders or branch circuits.

While most plant installations in the United States today have a copper ground ring, there are some facilities that prefer only an equipmentgrounding conductor run with the branch circuits and feeders to electrical equipment (either in the form of metal conduit, cable tray or wire, or a combination thereof), thinking that the circuit equipment ...
Introduction to Mineral Processing
The crushed copper ore (containing, for example, % Cu and % Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.
