Mar 09, 2018 Shape Ore Body There are three main types of ore bodies vein-type, massive, or tubular. Vein-type Vein type deposits are those that almost always have a dip at an angle greater than 50 degrees. Massive Massive ore bodies are those that spread over hundreds of meters. Tubular Tubular deposits are those that are relatively flat.Online Chat
Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.Online Chat
