It is estimated that about 600 tons of frothers and 1, 200 tons of collectors were used during 1954 in the Japanese flotation plants, treating about 6 million tons of metallic ores per year.
Frothers most commonly used are essential oils such as pine oil or camphor oil, and about 200 tons ofjpine oil is imported annually from the United States. Other frothers such as cresylic acid or higher alcohols are rarely used at present.
Collectors mainly used are xanthates, and most of them is ethyl xanthate. But the consumption of Aerofloats both liquid (mainly Aerofloat *25) or dry (mainly Aerofloat #208) is becoming larger. Collecting oils are still used in some zinc flotation plants.
In the flotation plants of coal, middle oil and creosote oil from coking industry are mostly used as the sole flotation agent.
