Lower c a p i t a l and o p e r a t i n g c o s t s over c o n v e n t i o n a l methods, a s i m p l e r f l o w s h e e t , and the a b i l i t y to p rocess a wide range of o r e - t y p e s , are the main advantages to t h i s type of comminut ion . E a r l i e r problems w i t h o p e r a t i o n and c o n t r o l of these c i r c u i t s have been s u b s t a n t i a l l y r e s o l v e d , and a much g r e a t e r l e v e l of c o n f i d e n c e e x i s t s i n the equipment . However, c a u t i o n i s r e q u i r e d i n s e l e c t i n g AG or SAG c i r c u i t s , because of t h e i r g r e a t e r s e n s i t i v i t y to ore c h a r a c t e r i s t i c s . For non-homogenous o r e b o d i e s , (as most a r e ) , wide swings in throughput and power consumption can o c c u r , w i t h the r i s k of exceed ing the l i m i t a t i o n s of downstream equipment or i n s t a l l e d motor power. Whi le c o n v e n t i o n a l c i r c u i t s can be des igned c o n f i d e n t l y based on bench s c a l e t e s t s , (such as Bond work index d e t e r m i n a t i o n f o r c r u s h i n g , rod m i l l i n g and b a l l m i l l i n g ) , no such t e s t s are as yet a v a i l a b l e f o r SAG c i r c u i t s . P i l o t - s c a l e t e s t i n g has I n v a r i a b l y been r e q u i r e d , and even then some n o t a b l e 1 d i s c r e p a n c i e s have a r i s e n between p i l o t p l a n t p r e d i c t i o n s and f u l l s c a l e per formance . E x i s t i n g p i l o t p l a n t t e s t s g e n e r a l l y i n v o l v e the use of a m i l l 1.5m - 2m i n d i a m e t e r , w i th l e n g t h s v a r y i n g anywhere from 0.6m up to 5m. Running t e s t s i n these m i l l s i s expens ive fo r a number of r e a s o n s . F i r s t l y , a l a r g e q u a n t i t y of ore i s r e q u i r e d , u s u a l l y i n the range of 10 to 50 tonnes of each ore t y p e . In the case of a new orebody, t h i s must be ob ta ined from development d r i f t s or a d i t s i f i t i s t o be r e p r e s e n t a t i v e of a mined p r o d u c t . In a d d i t i o n , the samples might have to be sh ipped a c o n s i d e r a b l e d i s t a n c e , w i th a t t e n d a n t c o s t s . S e c o n d l y , i t takes a long time to b r i n g such a m i l l to s teady s t a t e c o n d i t i o n s , so the manpower requ i rements are c o n s i d e r a b l e . S k i l l e d p e r s o n n e l a re r e q u i r e d to conduct the t e s t s and i n t e r p r e t the r e s u l t s . The c o s t s i n v o l v e d f o r such t e s t work can be s u b s t a n t i a l and i n many cases can be p r o h i b i t i v e . In the p a s t , o n l y l a r g e - s c a l e p r o j e c t s wi th m u l t i p l e g r i n d i n g l i n e s c o u l d j u s t i f y the e x p e n d i t u r e . With power c o s t s be ing such a major f a c t o r i n these p l a n t s , any i n c r e a s e i n g r i n d i n g e f f i c i e n c y a r i s i n g out of p i l o t p l a n t t e s t i n g c o u l d pay o f f v e r y q u i c k l y . In the case of s m a l l e r p r o j e c t s wi th a s i n g l e g r i n d i n g l i n e , the payback on p i l o t t e s t i n g would be much l o n g e r , and the a v a i l a b i l i t y of funds a t the b e g i n n i n g of the p r o j e c t , o f t e n 2 l i m i t e d . An owner faced w i th such c o s t s may be more i n c l i n e d to opt f o r the c o n v e n t i o n a l r o u t e , which r e q u i r e s o n l y sma l l samples ( e . g . d r i l l core ) to determine work i n d i c e s , on which the d e s i g n of a c o n v e n t i o n a l c r u s h i n g / g r i n d i n g c i r c u i t can s a f e l y be based . Time i s a l s o a c o n s i d e r a t i o n . With p r o j e c t s chedu les becoming more compressed nowadays, t ime i s not a v a i l a b l e f o r p ro longed t e s twork . For these r e a s o n s , a t tempts have been made to deve lop s m a l l s c a l e t e s t p rocedures ( fo r SAG c i r c u i t s ) , which would r e q u i r e l e s s m a t e r i a l , sho r t en the d u r a t i o n of each t e s t , and a c c o r d i n g l y enable a g r e a t e r v a r i e t y of ore types to be t e s t e d a t an e a r l y s tage of the p r o j e c t . In t h i s r e g a r d , some success has been ach ieved by MacPherson (1977, 1989) u s i n g a 450mm diameter d r y A e r o f a l l m i l l .

Autogenous G r i n d i n g The term autogenous g r i n d i n g d e s c r i b e s the p r o c e s s i n which ore i s ground i n a tumbl ing m i l l w i thout a d d i t i o n of any e x t e r n a l g r i n d i n g media . The ore p a r t i c l e s are reduced i n s i z e by a combinat ion of a b r a s i o n , impact and a t t r i t i o n . The l a r g e r ore p a r t i c l e s are worn down g r a d u a l l y by a b r a s i o n . These in t u r n a c t as g r i n d i n g media f o r the s m a l l e r p a r t i c l e s r e s u l t i n g i n impact and a t t r i t i o n a c t i o n , s i m i l a r t o t h a t o c c u r r i n g i n ' b a l l m i l l s . P r i m a r y autogenous g r i n d i n g r e f e r s to the s i t u a t i o n i n which r u n - o f mine or c o a r s e - c r u s h e d ore i s fed to the m i l l d i r e c t l y . The product from the m i l l may be of a s i z e s u i t a b l e f o r r e c o v e r y of the v a l u a b l e component, i n which case i t i s termed s i n g l e - s t a g e AG, or i t may r e q u i r e f u r t h e r g r i n d i n g to a f i n a l p roduc t s i z e i n b a l l or pebble m i l l s ( two-stage A G . ) . Use of p r imary autogenous g r i n d i n g began i n the 1 9 3 0 ' s , but r e a l l y i t was not u n t i l the l a t e 1950's and e a r l y 1960's t h a t the min ing i n d u s t r y as a whole began to c o n s i d e r t h i s o p t i o n s e r i o u s l y when p l a n n i n g new or expanded f a c i l i t i e s . In North Amer i ca , a l t h o u g h t h e r e have been some n o t a b l e s u c c e s s e s w i t h p r imary AG, the t r e n d has been towards semi-autogenous 4 g r l n d i n g . S u c c e s s f u l a p p l i c a t i o n of autogenous g r i n d i n g depends g r e a t l y on the nature of the o r e . There must be s u f f i c i e n t competent m a t e r i a l p resen t which w i l l a c t as the g r i n d i n g media f o r the s m a l l e r f r a c t i o n s .

M i l l Speed, Water Ratio, and M i l l Load Setpoint ( L i f t Pressure) were the manipulated variables. The b a l l charge changed from run to run and was estimated using a b a l l wear re l a t i o n s h i p developed by Lornex with corrections made as a r e s u l t of grindouts. For the 60cm c i r c u i t runs, the f u l l scale conditions were simulated as c l o s e l y as possible for each run. However, the eff e c t of a change in manipulated variable may not be the same in the 60cm m i l l as in the f u l l scale m i l l . For instance, Digre (1979) reports that the influence of m i l l f i l l i n g on 88 power draw and c a p a c i t y in a 0,8m d iameter m i l l i s f a r l e s s than In a f u l l s c a l e m i l l , on the other hand f water r a t i o may have a much more s i g n i f i c a n t e f f e c t i n a s m a l l m i l l than in a l a r g e m i l l because of the d i f f e r e n c e i n m i l l i n v e n t o r y .

In a d d i t i o n , changing parameters such as m i l l speed and f r a c t i o n a l f i l l i n g may change the r e l a t i v e p r o p o r t i o n s of impact , c h i p p i n g and a b r a s i o n o c c u r r i n g i n m i l l s of d i f f e r e n t s i z e s . As demonstrated by C r a b t r e e et a l (1964) , the s i z e modulus of the comminution p r o d u c t s changes depending on the p r o p o r t i o n of impact , c h i p p i n g and a b r a s i o n p r e s e n t i n the m i l l .
