Commercial extraction of significant reserves of turquoise, fireclay, and kaolin is also possible. Most mining was small scale until modernization efforts in the 1960s led to the systematic recording of known deposits, as well as the systematic search for new ones.Tin sources and trade in ancient times - Wikipedia,Tin extraction and use can be dated to the beginning of the Bronze Age around 3000 BC, during which copper objects formed from polymetallic ores had different physical properties (Cierny & Weisgerber 2003, p. 23).The earliest bronze objects had tin or arsenic content of less than 2% and are therefore believed to be the result of unintentional alloying due to trace metal content in copper ores,Micelle-mediated extraction and determination of tin in,,Micelle-mediated extraction and determination of tin in soft drink and water samples .

The tin hydride was generated by injection of a fixed volume of sodium tetrahydroborate solution into the sample. Effects of several parameters including sample volume, amount of added NaBH 4, Pd(II) and TBP concentrations in the drop, acid type and concentration in the sample, extraction time and drop volume were carefully studied.
