Models and Exploration Methods for Major Gold Deposit Types

carbonate ore assemblages accompanied by dominant illite alteration. Mineralization can consist of veins and breccia bodies and commonly display a larger vertical continuity than their low- or high-sulfidation counterparts. Carlin-type deposits have been regarded either as being distal parts of large OIR systems (Sillitoe and Bonham, 1990) or

MATERIAL SELECTION FOR MECHANICAL SEALS

Mechanical carbons aremanufactured by blending together types of amorphous carbon (i.e., lampblack, charcoal, or coke) and carbon graphite with a carbonaceous binder (i.e., pitch or resins). The source of the raw materials not only helps determine the physical properties of the carbon but also the type and amount of impurities.

MIXER MECHANICAL DESIGN—FLUID FORCES

designing for the loads in the shaft, these loads are transmitted through the gearbox, mounting structure, and finally the tank. The interaction of the process and the mechanical loads is extremely strong. Even in a mild case, the ± 40 percent load fluctuations stemming from the liquid flow around the impeller blades are dynamic.

The Sizing & Selection of Hydrocyclones

CYCLONE DESCRIPTION AND BASIC OPERATION Figure 1 shows a cutaway view of a typical cyclone. During operation, the feed slurry enters the cyclone under pressure through the feed pipe into the top of the cylindrical feed chamber. This tangential entrance is accomplished by two types of design, as shown in Figure 2. Since the
