Comminution Circuits for Gold Ore Processing

Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not). In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see Figure 17.13). On a size-by-size basis, concentrations of up to 100 times ...

Milling Machine Basics: Types, Classifications, & Cutting Tools

So what types of cutting tools should be used on a milling machine? That depends on the type of machining being performed—for example, it goes without saying that a drill is needed for holemaking operations, and some type of copy millor ball-nosed end mill is needed to machine a curved, three-dimensional surface. Beyond that, cutting …
