A placer gold separating method comprising subjecting placer gold- and gold ore-containing sand and gravel layers accumulated on the bottom of the water of a river and placer gold- and gold ore-containing sand and gravel layers formed deep in the ground to excavation or suction excavation by utilizing a water pressure difference, causing a mixture of the excavated or suction excavated placer gold- and gold ore-containing sand, gravel and water to flow horizontally by the action of a pressure fluid, and separating the placer gold and gold ores by utilizing a specific gravity difference while the mixture is flowing; and a system for this method. A placer gold mining boat used to practice this method and provided thereon with a combination of a suction excavation means, a mixture transfer means, a means for separating placer gold by utilizing a specific gravity difference, and a means for discarding the remaining mixture from which the placer gold has been separated. A placer gold separating method characterized by causing a mixture of placer gold and gold ores or pulverized gold ores and water to flow in a metallic cylinder, generating a magnetic field by a magnetic field generating means provided on an outer circumferential surface of the metallic cylinder, and magnetically depositing the placer gold in the mixture on the inner surface of themetallic cylinder, whereby the placer gold is separated.
