Alumina. bauxite ore is the main source of aluminum and must be imported from jamaica, guinea, brazil, guyana, etc. used in transportation automobiles, packaging, buildingconstruction, electrical, machinery and other uses. the u.s. was 100 percent import reliant for its aluminum in 2012. antimony a native element antimony metal is
In many sulfide ore samples containing zinc zn, silver ag, copper cu and antimony sb sulfides, the total bulk composition of the sample can be described by these four basic components, if others such as fes are present in negligible amounts. such a bulk composition plots as
Mar 03, 2012nbsp018332massive sulfide. massive sulphides have densities ranging up to 4240kg m3, and within host rocks of densities around 2750kg m3, a sulphide body having a width of 50m, a strike length of 500m, and a depth extent of 300m would give a gravity anomaly of about 3mgal.
The tests on gas-liquid phase compositions and h-o isotopes indicate that the ore-forming fluids of both gold and antimony deposits come from multiple sources the main source is the underground hot fluid formed from meteoric water, and a few amount of magmatic fluid and even mantle fluid might also be involved in the formation of the fluids.
In the world market, antimony is a critical metal and one of the important metals in short supply 1,2.in 2014, myanmar mined 9000 metric tons of antimony ores 1,3, establishing myanmar as a significant global source of antimony ore, and most of the ore was exported to china.a current estimate of the total resource of antimony in myanmar is about 1,016,047 metric tons 1,4.
Dec 01, 2008nbsp018332antimonyau-quartz veins from the d250ricobeir227 region are mainly hosted by a cambrian schistmetagraywacke complex, as well as ordovician phyllites and quartzites. the deposits were mostly exploited in the late 19th century. mineralogical characteristics and chemical compositions of individual ore minerals are similar in the two areas.

Other tin alloys include bronze, the alloy of copper and tin, the use of which goes back to antiquity. tin is also used in some brass compositions. but a useful variety of tin alloys are based on the tincopperantimony system table 2.these include the babbitt alloys that are used for bearings, tin die casting alloys, typemetals that have been used for high-quality book printing, and the ...
Just the elemental composition then i would go with stefan on the xrf. if you were, however, interested in the compounds e.g. antimony in ore then you could consider xrd as well.
Problem 4 the quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. a 9.62 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated hclaq and passed over a reducing agent so that all the antimony is in the form sb 3.the sb 3 aq is completely oxidized by 43.70 ml of a 0.1250 m solution of kbro 3.

Antimony ore antimony is a lustrous tin-white metal. although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid.the antimony ore found in our mine is stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process.
Antimony trisulfide is a green powder. it is a fuel used in various white star compositions of the potassium perchlorate-base. it is sometimes used in glitter compositions, fountain compositions and flash powder, however it is used less and less for flash powder as it is very poisonous and can usually be replaced by sulphur or completely ...
