Sub bituminous coal is a lignite that has been subjected to an increased level of organic metamorphism. This metamorphism has driven off some of the oxygen and hydrogen in the coal. That loss produces coal with a higher carbon content (71 to 77% on a dry ashfree basis).

Calcining, or roasting, is a hightemperature process (700 to 1000 °C) that converts zinc sulphide concentrate to an impure zinc oxide called calcine. Roaster types include multiplehearth, suspension or fluidizedbed. In general, calcining begins with the mixing of zinccontaining materials with coal.

The thing is, all datasets are flawed. That's why data preparation is such an important step in the machine learning process. In a nutshell, data preparation is a set of procedures that helps make your dataset more suitable for machine learning. In broader terms, the dataprep also includes establishing the right data collection mechanism.
