A New Process For Sulfate Removal From Industrial Waters

Closed Gold Mine. Water from a closed gold mine in Montana was also tested in CESR-process bench tests. In reducing the sulfate concentration to approximately 30 mg/L, the total dissolved solids (TDS) concentration of this water was reduced from approximately 4400 mg/L to 1400 mg/L (Table 2).

Colored gold - Wikipedia

White gold is an alloy of gold and at least one white metal (usually nickel, silver, or palladium). Like yellow gold, the purity of white gold is given in karats. White gold's properties vary depending on the metals used and their proportions. As a result, white gold alloys can be used for many different purposes; while a nickel alloy is hard and strong, and, therefore, good for rings and pins
