thod Of ore reduction bids fair to result

months. The company named is i tlc.

are wont to penaIize SO heavily. have
been sent over to Denver for TESTING
purposes, and the results ar said IL
have been much better than the own

Manager Reed, CT the Ontario, &C
knoWleiged the other day that IL
was looking into the process for tn
company, hat said it was too SOC,
, fer him TO express an opinion as t.
whether ii would be adopted I.
case IT is, it means the erection Of
plant 1t CT near Park City-probab 81

r nel-that viii have the capacity G
several hundred tons of Gre per day
TIE process by which the value
; ar extracted is a simple one and tn
gold, silver, lead and copper content
are al secured by one treatment
which consists Cf crushing roastin
and condensing the metallic content
j. and mixed with a definite per cent I
salt, determined by the character {
the rock to be treated. This nlAtuT

decomposition by which the meta! va

degrees OI heat are applied.
j., In the roasting process all ,hes

of certain values in the flues an
l. chambers, these fumes are further i
u vested of their values in a series :.

The erection of plants to do TIL
