The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible.Extractions are low and the solutions soon become foul.The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.However, some.
Antimony is sometimes found in pure form.It is also obtained from the mineral stibnite antimony sulfide and commonly is a by-product of lead-zinc-silver mining.Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite.It is mined in china, bolivia, south africa and mexico.

Sulfosalt minerals are those complex sulfide minerals with the general formula a m b n s p where a represents a metal such as copper, lead, silver, iron, and rarely mercury, zinc, vanadium b usually represents semi-metal such as arsenic, antimony, bismuth, and rarely germanium, or metals like tin and rarely vanadium and s is sulfur or rarely selenium orand tellurium.Bornite, also known.
The designed process plant processes sulfide material to produce up to two mineral concentrate products 1 when there is sufficient antimony grade to warrant, an antimony sulfide stibnite concentrate that would to be filtered, trucked off-site and sold and, 2 for all material processed, an auriferous sulfide concentrate that would be.
Stibnite stbnt, antimony sulfide, sb 2 s 3, a mineral, silvery gray in color, with a metallic luster.It crystallizes in the orthorhombic system.Found in many parts of the world, it is the most important ore of antimony.It is commonly deposited by alkaline waters and occurs in association with quartz, calcite, sulfides of the base metals, arsenic, gold, and silver.
Stibnite is the most important ore of the element antimony, and is an industrially important mineral.It was used as a metallic cosmetic in ancient civilization.Stibnite also forms some of the most exceptional crystal formations of all minerals, and large and well crystallized are highly sought after and appreciated by mineral collectors.
The sulfide class minerals comprise an economically important class of minerals.Most major ores of important metals such as copper, lead and silver are sulfides.Strong generalities exist in this class.The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
Stibnite is a toxic antimony sulfide mineral with an orthorhombic crystal lattice and a source of metalloid antimony.Stibnite paste has been used for thousands of years for cosmetics to darken.

Stibnite is a very soft delicate mineral and should be kept in a container with a very soft cushion like cotton and not allowed to rub up against the sides of the box.Stibnite is a bit like graphite in that it will leave a streak when rubbed against paper.
Stibnite meanings, zodiacs, planets, elements, colors, chakras, and more.Stibnite, also known as antimonite, is an antimony sulfide mineral that crystallizes in the forms of masses, but is most commonly known when seen in its semi-rare, long prismatic crystal structure.These long, tubular crystals can be seen ranging from a few inches, to a few feet.
Sulfide and sulfosalt mineral specimens including sphalerite, argentite, stibnite, pyrite, greenockite, orpiment, tennantite, tetrahedrite, realgar, pyrrhotite.
Stibnite mineral specimens from morocco, exhibiting a massive crystalline texture, grey colouration with a metallic lustre.Soft as expected, the mineral leaves a grey streak.As it is a sulfide mineral, children should not handle these samples.
The mineral stibnite stibnite, also known as antimony, belongs to the sulfide category of minerals.This material is soft and gray, and is known to crystallize in an orthorhombic referring to a crystalline structure of three axes that are perpendicular and varying in length space group.For metalloid antimony, this is the primary source.
