method is known as dry mining because no gravel pump is used. (Hence, the gravel pump is now known as wet mining).This method is very ideal for sandy karang. This has proven to be a highly effective method of mining as large volume of tin ore bearing earth can be treated. The other operations are the same as gravel pump method.
