Pine alcohol oil is widely used in flotation operations of various metal or non-metal ores. It is mainly used for flotation of various sulfide ores such as copper, lead, zinc, iron ore, and various non sulfide ores. It also has a certain capturing ability, especially for easily floatable minerals such as talc, sulfur, graphite, molybdenite, and coal, which have a significant capturing effect. The foam formed by terpineol oil in flotation operation is more stable than other foaming agents.
