Placer Gold Mining Solution & Flow Design Mineral
Gold in placer mines is usually mixed with a large amount of ore. The task of placer gold beneficiation is to separate gold from a large amount of mixed gravel to ensure a higher metal recovery rate and better economic benefits. The heavy minerals associated with placer gold can be arranged as follows according to the common degree: magnetite, ilmenite, rutile, garnet, zircon, pyrite.
Minerals Associated or Found in Gold Placer Gold
Associated Minerals: Placer gold invariably is accompanied by other heavy minerals, which comprise the black, white, or yellow concentrates found in the sluice box when cleaning up. Table 3 lists these minerals roughly in the order of their commonness. Some of the characteristics noted under Remarks apply chiefly to the minerals as they are found in sluice-box concentrates.

Although these terms are described herein as they relate to the processing of placer gold ores, most of the terms identified apply to mineral processing in general. The concentration of placer gold ore consists of a combina- tion of the following three stages: roughing, cleaning, and scav- enging.
GOLD PLACER DEPOSITS Earth Science
Placer gold in its natural form is almost always alloyed with a certain amount of silver, which decreases its fineness. The silver, being much lower in value or price per ounce, lowers the value of the gold by a corresponding amount. Fineness is based on a scale of 0 to 1,000. As an example, gold 750 fine would be three-fourths gold and probably close to one-fourth silver. The important thing
