First, gravity concentration (Knelson concentrator and Mozley table) followed by flotation of the pulp of this concentrate in open and closed circuits. Gravity concentration produced a concentrate grading from 10,263 to 62,143 g/t Au, recovering from 54–67% of the gold from the ore. Flotation produced a concentrate grading 91 to 120 g/t Au.

The C&F mining cycle begins with the pivot ramp driven downward from the footwall to access the bottom of the stope block at its midpoint along strike. Once the bottom sill is mined, production uppers (2 m) are drilled and blasted for the first cut, and then the ore is mucked and the stope backfilled with mine waste rock using a remote LHD.

Historically, the mine operated at a rate of 200 tons per day. Ore was crushed through primary and secondary crushers, and ground in a ball mill. A standard flotation circuit was used to concentrate the ore prior to being shipped off site. Historical gold recoveries …
aimed at rejecting coarse waste by exploiting the physical properties of the ore (Shirley, 2009). Put simply, it is a process that enriches the ore. This is not a new concept in mineral processing. There is a range of options for pre-concentration, including flotation, screening, optical sorting, x-ray sorting, dense media separation and gravity

Heritage Council of WA Places Database. 27, 2002 · The mine was subject to a Board of Control in 1924. It was closed in 1927 after the lode had been worked over a length of 250 ft, to a width of 10 ft and a depth of 250 ft, and producing 90,000 tons of ore (in early years, ore from the Galena mine was moved by tramway to the Warribanno Chimney [Site No.9]) for smelting.
In 1905, Samuel Newhouse, a mining profiteer from Pennsylvania, bought these mines, originally named the Cactus Mines, renamed them the Newhouse Mines and Smelters, and built the small town Newhouse around the mines. All of the drawings and plans in the collection were drawn by Robert F. Moser, a mechanical engineer in Salt Lake City.
This mine operated until 1958 producing 808 tons of lead. A set of photographs (Battye 816B/B581, 816B/B582, 816B/B681, 1618B, 3827B/23, 3827B/24, 3827B/26), said to have been taken in 1936, show what appears to be the construction of the processing mill at the Surprise Mine and an aerial view of the Surprise Group.

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of …
It was a small mining operation in the beginning, but by 1870 to 1880 a ten stamp mill had been erected and the engine placed to run the mill. The infrastucture grew to include a bunk house, compressor house, a saw mill and of course narrow gauge tracks, ore cars and a chilean crusher with separator and flotation table. The mine was in full swing.
Flotation mills and tables, and well conditioned crushing and grinding sections were added to the mill. The Leadville by this point had been profitable, producing more lead and some silver and gold. The Halsey Williams Mill continued to process ore from the Leadville, and also added ore from the United Lead Mine and possibly other mines in the ...
