Lime plays a critical role in flotation by controlling pulp chemistry and collector adsorption. • Lime is the most economical and commonly used reagent for pH control in flotation. • Ca 2+ ions in lime can enhance depression of minerals and flotation selectivity in a variety of ores. •
Apr 27, 2019- Rosin gum & resin gum and so called Turpentine oil from Pine Tree highly used as raw material in chemical industry. Produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. Rosin used in printing inks, paper, varnishes, glues, soap, soda, sealing wax. Turpentine oil is a derivative of turpentine obtained by steam distillation of the species Pinus.
Use of lime often results in the depression of native gold and gold-bearing sulphides. The optimum flotation pH ranges between 8.5 and 10.0. The type of frother also plays an important role in the flotation of native gold and gold-bearing sulphides. Glycol esters and cyclic alcohols (pine oil) can improve gold
Products & Informations. Terpenic oil made from turpentine, used in the flotation of gold, silver, copper, molybdenum sulfide and other non ferrous metals sulfide, its dosage will be less than other collector, which has strong frothing effect.
dispersing effect but is also known for its depression effect on quartz and silicates in flotation circuits . Additions of three arious dosages of sodium silicate to the sulfur flotation werev tested. Pine oil of 20 g/t and kerosene of 20 g/t were also added in each test. ... Characterization and Flotation of Sulfur from Chalcopyrite ...
Jul 17, 2010· In the early days of flotation, coal tar or pine oil (turpentine) were used in very small amounts per ton of ore to float gold. The finely ground ore was mixed in tanks with paddles designed to suck in air, or compressed air was piped into the bottom of the tank. The gold would attach itself to a rising air bubble and float.
Turpentine is made by distilling pine resin from pine trees. Turpentine is antiseptic, warming, clearing and good for everyday muscle aches. Pine resin turpentine essential oil is commonly known as a solvent, this high-quality pine resin oil has therapeutic properties. This Essential Oil is strong and should be used with care.

The pine-oil bubbles will rarely be over ¼ or ½ inch diameter. Castor-oil, olive-oil, candle- makers' oil (oleic acid), palm-oil, sperm-oil, and other oils of a lubricating nature, have in general been replaced by oils more or less soluble or miscible in water—such as turpentine, pine-oil, and all …

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
Pine oil is an essential oil obtained by the steam distillation of stumps, needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris.As of 1995, synthetic pine oil was the "biggest single turpentine derivative." Synthetic pine oils accounted for 90% of sales as of 2000.

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
Pine oil is an essential oil obtained by the steam distillation of needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris. Pine oil is distinguished from other products from pine such as turpentine, the low-boiling fraction from the distillation of pine sap, and rosin, the thick tar remaining after turpentine ...
In each case the ore was ground to about 70 per cent minus 200 mesh and conditioned at 22 per cent solids with the reagents as indicated. Flotation reagents included reagents 301 and 208 and pine oil. In the second case some soda ash and copper sulphate where also used. GOLD FLOTATION …
Magnesite Flotation Process- Separation Stage. In this stage, the main equipment is floatation, agitation tank, thickener. The following two methods is the designed magnesite flotation process by Xinhai. High grade magnesite ore flotation process: the grinding fine ore will feed into agitation tank, and meshed with flotation reagent.
Excessive froth: There are few cases where gear box oil leakages enter flotation circuit through spillage cleaning and feeding to Flotation circuit. Please confirm such leakages and arrest them. One drop of oil contamination is very dangerous to flotation. It not only creates excess forth but also reduces gold …

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Foaming agent: Foaming agent for separation of gold and silver ores, commonly used are 2 # oil, turpentine, camphor oil, dipyridine and formic acid, the amount of which is generally 20-100 g/t. Camphor oil has good selectivity and is mostly used to obtain high-quality concentrates and priority flotation operations.
Pine oil is a cyclic neutral alcohol frother. The active frothing agent in pine oil is terpineol C 10 H 18 O. Its usage in mineral processing stems from the fact that it is less sensitive to the presence of clay minerals than aliphatic frothers like MIBC.
