A 20Mta mill will have a capital cost within 10000 th and 20000 th Lane Fleay Reynolds amp La Brooy 2002 Typical operating costs for mills used in gold extraction are summarized in Table 3 The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV
A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting Such comminution is an important unit operation in many processesThere are many different types of mills and many types of materials processed in them Historically mills were powered by hand or by animals eg via a hand crank working animal eg horse mill wind or water
Autogenous mills or AG mills can accomplish the same size reduction work as two or three stages of crushing and screening Often used in grinding at modern mineral processing plants AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages
