As an example and for illustrative purposes only ore processed at the Shootaring Canyon Mill which is produced from properties owned by a joint venture between Uranium One Utah and a third party subject to a joint venture agreement that allocates 50% equitable ownership to each of the venture parties shall be deemed to be beneficially owned 50% by Uranium One Utah and the Royalty
· While ore grades vary widely copper ores typically contain only about a half percent by weight of the element itself thus roughly 200 tons of ore are dug up moved crushed and processed to get to one ton of copper For rare earths some 20 to 160 tons of ore are mined per ton of element
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image 135 6 3 ] AG/SAG Mill AG/SAG mills are normally used to grind run off mine ore or primary crusher product Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids 2D and 3D simulations of particles in a
For example lets say that a mine was processing ore valued at 1 troy ounce of gold per ton This would generally be considered a very high grade ore worth mining in most cases Using this hypothetical value of 1 ozt /ton each pound of ore would contain approximately ounces of gold Now let s assume that gold is valued at $1500 per

Doré bars are unrefined gold bullion bars containing anywhere from 60 to 95 percent gold We finally send the bars to a refinery for further processing into pure gold Alternative Ore Processing We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements
In addition a mill had been built on the floor of Death Valley five miles and 3 500 feet below the mine where the ore from the mine was trucked for preliminary treating The mill included a jaw crusher a ten foot Lane mill a table and a Diester slime table
