Keep the 1.25 coefficient in mind when reading forward. We used it earlier for calculating PSU wattage. For example, PSU with 80% efficiency will draw 1000W of power from the wall socket but will forward only 800W of power to the computer. This means that 200W of energy is wasted in the conversion process. There are different efficiency ratings.
For example, heap leach ore depths were increased from 50–60 ft. to 500 ft. This function is significant for controlling the economic e ffi ciency, surface area availability and also for
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground.
