Rose et al. investigated conditions for concentrating yttrium from solution using αsulphonated fatty acids via ion flotation, and a maximum recovery of % was obtained under optimum conditions within 30 minutes; furthermore, they found that by increasing the pH to 8, the extraction rate was 3 times faster with a smaller loss in extraction compared with flotation at pH 84 Chirkst et ...
· Shaker tailings are finely ground to 80%, mixed with antimony and gold by adding yellow medicine, black medicine, lead nitrate and copper sulfate, and the tailings after antimony and gold are floated to scheelite and oleic acid As a collector, sodium carbonate adjusts the PH of the slurry to about 9, and water glass is used as an inhibitor of silie.
antimony using 1,000ml of solution containing of antimony(III,V) and 10 mg of iron(III). Hydrochloric acid and aqueous ammonia solution were used to adjust the pH to values within the range of Quantitative recoveries of antimony(III,V) .
· Some lead acid batteries are used in a standby condition in which they are rarely cycled, but kept constantly on charge. These batteries can be very long lived if they are charged at a float voltage of to volts/cell (at 25 degrees C) ( to for a 12V battery).

· Commonly Used Froth Flotation Reagents. Collectors: Collectors commonly used in the flotation process of gold and silver ores include xanthate, black powder and butylammonium black powder. Kerosene and transformer oil can be used as auxiliary collectors. Oleic acid can also be used as a collector for goldcopper oxide ores.

furic acid, and contained in a platinum or ceresin vessel. Finally, wash twice with water. Evaporate the filtrate and washings in a platinum dish on the steam bath. To recover any arsenic, antimony, or tin in the precipitate, remove the paper from the funnel, and sluice the lead sulfate into a 400ml beaker, using as little water as possible.
· There were certain tradeoffs, however, in battery characteristics. Introduced in the 1880s, lead antimony, for example, enhanced grid strength and improved manufacturability, but it resulted in antimony poisoning, a phenomenon that caused higher hydrogen evolution under both float and recharge conditions and led to increased outgassing.
· Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame .

flotation rate, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995).

· Fatty acid collector flotation method is mainly used for flotation of leadzinc oxide ore with low iron content and a small amount of carbonate and sulfate gangue minerals. Chelating agent flotation Chelating agents generally have more than 2 ligands, such as oxygen atoms, nitrogen atoms, sulfur atoms, etc.
Flotation methods used to concentrate lowgrade stibnite ores can produce a concentrate that contains more than 60 percent antimony with recovery rates of up to 95 percent. The particular combination of flotation reagents that is used depends on the physical characteristics of the ore being treated.
Potassium feldspar mining equipment mainly include jaw crusher, ball mill, desliming bucket, hydrocyclone, strong and week magnetic separator, flotation cell, etc. the main process is curshingmillingmagneticflotation, etc. 1. Crushing: firstly, use the jaw crusher to crush massive ore. 2. Ball mill: after crushing, use ball mill to grind ore. 3.
· Anionic collectors include fatty acids, hydrocarbon sulfonates, sulfovinate, which are mainly used for flotation separation of tungsten and tin, as well as the nonmetallic minerals. Cation collectors include nitrogenous monoamines and quaternary ammonium compounds, which are mainly used for flotation separation of iron ore, quartz, silie and other minerals.
Antimonial positive plates can provide good cycle, easy recovery from deep discharging, and high temperature characteristics. Calcium negative plate can reduce gassing, longer storage life and higher CCA. 4, some common features of a battery The first feature of the Leadacid battery is the capacity versus discharge time.
· Flotation reagents may be roughly classified, according to their function, into the following groups: Frothers, Promoters, Depressants, Activators, Sulphidizers, Regulators. The order of these groups is no indiion of their relative importance; and it is common for some reagents to fall into more than one group.
