TUBE PROCESS
H. w. Ingalls, Writes of New Process
Which Successfully Treats
Morning Ore.

The following article written by H. w. ngals lor
The Mining and Engineering World Mr. Ingalls, is manager
the Copper King Mining company operating near Muah'
The Morning MILL in which the McQusen tube process is oe
ng tried out located at Mulan and Mr. Ingalls, beng
sdent of that place has had ample opportunity to observe
he process:
The New McQuisten tube process Tor the recovery OF
nc and lead shines has been demonstrated to be success AZ
he Morning mine owned by the Federal company at Muan
IDAHO This the first tube mill of its kind to be placed IN
PRACTICAL operation The machines manufactured oy .he
American Direct Concentrating company OF Salt Lake wy
tah This company has of necessity erected experimental
ants on different classes Of ore but the Morning mne pant
Mulan the first to be installed under actual Z4houf
working conditions for the purpose OF saving ore OF CONNER
ia value from material which, for many years. mas oee o

process of milling and concentration and have resulted III

The process is in direct opposition to the concentrating

The feed is kept in agitation by heavy screw thread
Iwith which the inside of the tubes equipped lhese
