Visiting the site of one of our customers mills. He purchased and is operating a 2 TPH turnkey system from MBMM and is custom processing ores and concentrat.
The PTFI mills treat ore from the Grasberg (open pit) and Deep Ore Zone (underground) deposits and recover gold contained in copper concentrate via flotation and gravity circuits. Table 1 . Top gold producers 2003
Apache Mill Tailings USA Inc. is a precious metals mining company specializing in gold silver copper and high value rare earth minerals reclamation recovery. To maximize profits accelerate project success and reduce risk we work with above ground mine and ore mill tailings deposits.
Some of the ore assayed at $75 per ton in gold with 10 ounces of silver. In 1888 the mine was developed by three shafts of 50 60 and 75 feet. Ore was extracted from 75 feet of level workings. Fifty tons of the ore was worked in mills in the county and 100 tons were shipped to smelters.
The ore is sent into a single-cylinder hydraulic cone crusher for the secondary crushing. Thereafter the gold ore is transferred to a multi-cylinder hydraulic cone crusher where the ore is crushed further into finer material. From there the crushed gold ore is sent to a ball mill evenly as it passes through a vibrating screen for grinding.
20 to 30 TPH for gold ore SAG & Ball Mill duty; 25 to 40 t/h for copper porphyry SAG & Ball Mill duty; In Single Stage SAG duty the approximate capacity reduces to only 8 to 13 TPH for gold ore duty. The autogenous mill itself is a coarse-grinding device consisting of tumbling drum with a 25% to 40% volume filling of ore.
Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time 1890 the Author said “There is of course nothing for us to learn from this imperfect and rudimentary gold-extraction process described here which is doubtless destined to disappear ere long before the progress of scientific mining now making itself slowly felt .
The Island Gold Mine ore is processed at the Kremzar Mill. The mill is composed of a two-stage crushing section followed by a two-stage grinding section. The mill uses cyanide leaching and a carbon-in-pulp process to recover gold.
