Arsenic, Zinc, and Aluminium Removal from Gold Mine

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, and Hydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi metals concentrations in mine waste water.

Zinc, (aka spelter), is an element with symbol Zn and atomic number 30. Zinc was known from ancient times, when Brass (i.e. an alloy of Copper and Zinc) was used. Lohneyes was the first to apply the term "Zinc" correctly to the metal that we know today in 1697 Zinc is a bright bluish white metal that is brittle at room temperature
