Coal Preparation in India – A Historical Perspective. The earliest record of systematic coal washing study in India was an attempt by Prof. William Galloway using a pre-Baum type Jig washer before World War I on tested Assam coals. Sometimes later Prof. Henry Louis of Newcastle-upon-Tyne conducted similar experiments on Jharia coals.
