Anahi Mine (Anay Mine; Anai Mine), La Gaiba mining

(Some mineral descriptions for Anahi Mine state it is in the high Andes, but that is not true.) The mine exploits quartz veins in dolomitic limestone. Its products include amethyst (on average, 44% of production by weight), ametrine (33% of production) and citrine (23% of production), along with colorless or milky quartz of little or no value and not quantified above.

From the Andes to the Pantanál: In Search of Ametrine

2013-4-30  Several different shafts have been drilled into the property along these veins, and Rivero estimates that in a good year 3,000–3,500 kg of gem-quality quartz are mined. Ametrine is the most lucrative of the products, though on average amethyst makes up 44% of production by weight, ametrine 33%, and citrine 23%.

Commercial Opportunities for Mining in Bolivia Biz

2019-10-29  Last year Bolivia increased its production of zinc, gold, silver, lead, antimony, wólfram and ulexite. The private sector is the most important productive actor for Bolivian minerals. It was reported that between January and September of 2018, this sector contributed to around 57% of the mineral production value.

Production of industry-specific quartz raw material

2019-1-18  Mineral impurities are usually fine grained, and most are secondary minerals which are easily pulverized into finer material. Most of these mineral impurities in vein quartz are located along crystal boundaries (Andres et al. 1999; Dal Martello et al. 2011, 2012). In the study, the 1–10 mm size fraction showed a reduced Fe level due to the liberation of finer-grained Fe-bearing impurities present at
