Plagioclase feldspar is a group. Anorthite has an aluminum:silicon ratio of 1:1 while Albite has a ratio of 1:3. Microcline is considered orthoclase feldspar; it's similar to albite, the only difference is sodium replaced by potassium. Feldspar with an aluminium:silicon ratio of 1:1 will dissolve in hydrochloric acid. Other forms of

To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …

Porphyry is an igneous rock similar in composition to granite. Unlike common granites, pophyry has large, light-colored crystals of quartz or feldspar floating in a red or purple fine-grained matrix of smaller crystals. The word "porphyry" comes from the Latin word for purple, which was the color of nobility to the Romans.

By Brian Kevin From our April 2022 issue. If you don't instantly associate Maine with gem and mineral mining, you might be forgiven, but it probably means you haven't spent much time in Oxford County, where scratching away at the state's western mountains and foothills has been a way of life for generations.

Feldspar extraction, however, dominated the quarry ventures. Production grew slowly but steadily between 1880 and 1960, after which it declined. Presently the pegmatite is excavated, ground, and its minerals are separated by a y floatation system. The leftover quartz grains provide an ideal beach sand and can also be used to produce glass.
