A plot of the resulting data is given in Figure 11. When the lime/limestone raw-material cost ratio was less than 1-78:1, the cost advantage of combination treatment over lime treatment no longer existed. As the lime/limestone ratio increased, so did the advantage of combination treatment. At ratios below 1.78:1, lime was more economical.

The standard PFRK needs clean limestone, ideally with a limestone ratio not greater than 2:1. The minimum limestone size is 30 mm, although a modified design called the PFRK fine lime kiln can operate on sizes as small as 10 mm to 30 mm on clean limestone. In PFRK fuel feed is through lances in the limestone bed.

One stage rod mill grinding is therefore suitable for preparation of feed to gravimetric ore dressing methods, certain flotation processes with slime problems and magnetic cobbing. Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4.

For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes.

surface water is a fairly popular method of increasing the pH values and decreasing the concentration of phosphates and heavy metals. According to the Environmental Protection Agency (EPA) recommendations, the increase of water pH should not exceed 1.5. If surface water is the source of water supply, is a process that reduces water contamination.

The added limestone in the U.S. is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding.
