Historical reports state there were once over 1,ooo mines in the Ochocos that bore cinnabar, gold and thundereggs. Today, less than 50 are still open. The most frequented mines are the Mother Lode Mine and Independent Mine. Neither of these locations are currently maintained, but a great place to visit and imagine activities of the past.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

The Goldome complex seems to have ceased operation by 1998. The lights of the Ivanpah solar Plant can be seen in the distance on the left. The seclusion of the mill site has likely helped protect it from vandals. The name Goldome, means "an abnormal growth of gold;" the suffix "–ome" is a variant of "–oma," usually meaning a tumor.
