Sodium n-butyl Xanthate (SBX or SNBX) such as gold copper lead or zinc minerals from non-valuable minerals such as Since each ore is unique there is no standard flotation procedure and no standard grade or type of xanthate used to extract specific values Each producer has its own grades for xanthate composition including purity
Australia also has a noticeable share in gold mining in the region The average ore grade for gold can vary from 1-4 g/ton to 8-10 g/ton As a result of the extraction of gold from low grade ores that are found in a number of mines in China these is an increasing demand for flotation collectors such as xanthates

Mining complexity and declining ore quality necessitates specialty chemicals to process ores Xanthates are widely used for the extraction of copper gold and other metals Over the recent years there has been a significant decline in the quality of copper ores extracted
The goal of assaying and testing any potential gold and silver bearing materials is to determine their metals content While it is sometimes possible to look at a sample and guess its possibilities more often than not in order to have an accurate idea of how valuable in ore is it must be analyzed

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing paper recycling and waste-water treatment industries Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century
Used as the collector for the flotation of non-ferrous metal mineral which need strong collector but no selectivity It is a good collector for the flotation of oxidized sulfide ore or copper oxide and zinc oxide (vulcanized by the sulfiding agent）as well as copper-nickel sulfide ores and gold bearing pyrite ores

Kemcore continues to be instrumental in procuring a complete suite of reagents for our gold/copper flotation plant I do not hesitate to recommend Kemcore services for Xanthate DTP's plant reagent supply especially when procuring out of China
Gold Ore and Silver Ore are a skill point for anyone who smelts ( up to a certain level) it helps get over that hump where the ore is green and a pain in the arse to get 1 more point so you can then smelt something higher So in other words Gold Ore and Silver Ore are worth more on the AH for this reason

Xanthate salts are produced by the reaction of an alkoxide salt with carbon disulfide The reaction involves the attack of the alkoxide nucleophile on the electrophile CS 2 Often the alkoxide is generated in situ by treating the alcohol with sodium or potassium hydroxide ROH + CS 2 + KOH → ROCS 2 K + H 2 O For example sodium ethoxide gives sodium ethyl xanthate
Gold ore is a type of ore that can be obtained by mining gold ore rocks requiring a Mining level of 40 or higher and granting 65 experience Gold ore can be smelted into gold bars through the Smithing skill requiring level 40 Smithing Gold bars can then be crafted to make various pieces of
