Dithiocarbamate ES (SN9#) |
|
|
NAME: Dithiocarbamate ES (SN9#)
CAS NO.: 20624-25-3
Other name: Sodium diethyldithiocarbamate trihydrate
CHEMICAL FOMULA: (C2H5)2Ncssna 3H2O
SPEC: ≥ 94.0% ≥ 92.0%
PHYSICALS: White or ecru color in form of powder or crystal,easy disolution in water, easy to decompose into carbon disulfide, diethylamine in acidic intermedias.
FUNCTIONS: Excellent collector for sulfide minerals like copper, lead, stibnite, etc, with better performance than xanthate and dithiophosphate. Good collecting + quick flotating + fine selectivity + economic consumption. It could IMPROVE dressing between lead and zinc when floating under high alkalinity. It could be used in metalsmelting refinery. And as accelarating agent in rubber sulphuration.

Carbon Disulfide |
|
|
NAME: Carbon Disulfide
CAS NO.: 75-15-0
EC NO.: 200-843-6
Other name: Alcohol of sulfur
CHEMICAL FOMULA: CS2
DENSITY(20℃) g/ml: 1.262-1.265 1.262-1.267 1.262-1.267
SPEC: ≥97.5% 97.0% 96.0%
PHYSICALS: Pure carbon disulfide is a colorless, transparent, and fragrant liquid, slightly soluble in water and a good solvent for organic matters. Carbon disulfide as crude product appears pale yellow, and has a pungent odor. It is highly volatile,inflammable,poisonous and harmful to organisms.
FUNCTIONS: The most important use of carbon disulfide is to make viscose rayon and viscose stable fiber, accounting for 75% of the gross amount. Carbon disulfide used for making cellophane accounts for 5% of the gross amount;, less than 10% of carbon disulfide is used in carbon tetrachloride; and the rest is used in chemical engineering, rubber, flotation agent, agricultural chemicals, pharmaceuticals, dyes, and petroleum industry. In addition, carbon disulfide and its derivatives are used to make solvents, extractants, pre-curing catalysts, and chemical reagents etc.
STORAGE: Humidity-proof,heat-proof,fire-proof

Pine Oil |
|
|
NAME : Pine Oil
CAS NO.: 8002-9-3
Other name: Terpineol, Pine Camphor Oil
CHEMICAL FOMULA: C7H17O4
SPEC: ≥49.0% 44.0% 39.0%
PHYSICALS: Yellowish transparent oily liquid. Sparingly soluble in water. It may decompose on heating and in contacting with acids, and subsequently reduce the flotation efficacy.
FUNCTIONS: The pine oil is widely used in the flotation of various metallic and non-metallic minerals. It is mainly used in the flotation of warious sulfide ores, such as lead,copper,zinc, and iron sulfide, and non-sulfide minerals. It exhibits some collecting properties, especially for readily flotable minerals, such as talc, graphite, sulpher, molybdenite and coal etc. The froth produced by pine oil is more persistent than that produced by other frothers.
STORAGE: Humidity-proof,heat-proof,fire-proof
PACKAGE: 200kg/drum |

sulphur |
|
|
Sulfur is an essential element for all life. sulfur can be found as the pure element and as sulfide and sulfate minerals. Almost all elemental sulfur is produced as a byproduct of removing sulfurcontaining contaminants from natural gas and petroleum. The elem ent's commercial uses are primarily in fertilizers, because of the relatively high requirement of plants for it, and in the manufacture of sulfuric acid, a primary industrial chemical.
