Get Price ListMost sulphides are oxidied to sulphate. From the sulphated ore all of the inc copper and iron can be leached with water while lead silver gold and antimony will remain in the insoluble residue. Leaching of an Arsenical Copper Sulfide Concentrate
It is extremely important when treating high sulfide ores with cyanide to keep a sufficient protective base in the solution. Many sulfide minerals also contain things like copper or antimony that can react with the cyanide preventing the cyanide from leaching out the gold and silver.

2.4. Alkaline Sulfide Hydrometallurgical Treatment of Lead Softening Skims The formation of arsenic and antimony skims in lead refining is commonly encountered. An example of the application of the alkaline sulfide hydrometallurgical treatment follows. Table X. Lead Softening Skims Head Sample Assay Pb Sb As 52.9 31.7 3.3
The dark red silver ore is a sulphide of silver and antimony the light red contains arsenic in the place of antimony. The ores of silver occur in veins traversing granitic and gneissic rocks clay slate mica schist limestone and are usually associated with the ores of iron copper load galena being always argentiferous inc.
Feb 14 2016nbsp0183329 Deadliest Rocks And Minerals On Earth. Galena is a lead sulphide mineral that is one of the primary ores of lead found around the world.
Smelting and Roasting Gold and Silver sulfide Ores to recover values Nevada Outback Gems. Smelting and Roasting Gold and Silver Ores. Interested in The processes of smelting or roasting your ore to recover its gold and silver your oxidied sulfide solutions will be strongly acidic and may be full of toxic heavy metals like lead antimony
The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore 1 A.T. red lead 1000 grains sodium carbonate 500 grains potassium ferrocyanide 550 grains with a cover of salt or borax. The button is scorified together with the matte formed before cupellation. E. A. Smith found this method unsatisfactory and recommends the oxidation of sulphide of antimony by
Lead smelting and lead alloy classification Lead mining reacts with O2 in order to remove the sulfur component of the metal sulfide. Roasting is a method where a sulfide ore i.e an ore containing PbS is heated in air which converts the metal sulfide to either a metal oxide or a metal itself. inc antimony and arsenic. The
OREAS 112 is a high grade Cu ore certified reference material CRM prepared from material sourced from the Tritton Copper Project near Nyngan New South Wales. The deposit consists of sulphide ore bodies massive pyrite and chalcopyrite breccias underlying oxide ores.
Antimony ores are extracted mainly through underground mining. While lumps of rich ore in vein deposits do not require dressing leaner ores are dressed using gravity and flotation methods yielding concentrates that are 3055 percent Sb. Production of antimony
Meneghinite is one of several lead antimony sulfides. The elements lead antimony and sulfur have the capability of forming many different minerals. There are at least a doen different minerals with just lead antimony and sulfur comprising their chemistries.
Pyrite galena sphalerite and chalcopyrite are all common sulfide minerals that are found in many precious metal veins and other hard rock deposits. When metals combine with sulfur the resulting mineral is called a sulfide. These minerals are the most important sources of most base metals like copper lead and inc.
Applications The proposed methods have been applied to the determination of antimony in a number of materials of different types such as copper sulphide ores lead sulphide ores silicate rocks etc. and the results are shown in Table 2. The methods have been validated by analysis of

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
Antimony a metallic element belonging to the nitrogen group Group 15 Va of the periodic table. Antimony exists in many allotropic forms. It is a lustrous silvery bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.

Stibnite the antimony sulphide mineral responds much better to flotation after being activated with lead nitrate. The theory generally accepted on activation is that the activating substance generally a metallic salt reacts with the mineral surface to form on it a new surface more favorable to the action of
The sulphide minerals are the major source of world supplies of a very wide range of metals and are the most important group of ore minerals. In addition to their concentrated occurrence in ore deposits and areas of mineraliation a limited number of sulphide minerals are found as accessory minerals in rocks.
