Sand, gravel, and crushed stone operations | GeoKansas

After groundwater fills the pit, a dredge floated on the water is used to remove sand from the bottom of the pit. Many small lakes in Kansas flood plains, especially near the Arkansas River, were dug as sand pits.

Lecture 4: Mining waste

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports.
