Genesis of nonsulfide zinc deposits and their future utilization
Nonsulfide zinc deposits tended to be sidelined by sulfide sources in the late 19 century. The development of flotation and smelting technologies allowed the exploitation of sulfide ores and made them a useful Zn source at low costs. The commercial interest in nonsulfide zinc deposits has been renewed by the possibility of cost-efficient onsite Zn production, due to recent

Classification, Genesis, and Exploration Guides for Nonsulfide Zinc
Jun 01, 2003Supergene deposits are the most common type of nonsulfide zinc deposit and are distributed worldwide. The vast majority occur in carbonate host rocks owing to the high reactivity of carbonate minerals with the acidic, oxidized, zinc-rich fluids derived from the oxidative destruction of sphalerite-bearing sulfide bodies.

The Nonsulfide Zinc Deposit at Accha (Southern Peru
Mar 01, 2009The nonsulfide mineral association consists mainly of smithsonite and hemimorphite replacing both primary ore minerals and carbonate host rocks. Hydrozincite has been detected only in samples near the surface. Smithsonite occurs in zoned concretions with goethite, Mn (hydr)oxides and Zn clays, as well as replacive cement in the limestone intervals.

Classification, genesis, and exploration guides for nonsulfide zinc
Non-sulfide zinc deposits (zinc “oxide ” deposits) are becoming favored exploration targets due to new developments in metallurgy allowing for solvent-extraction and electrowinning. While geologic understanding of the genesis of these types of deposits is improving, there has been little work aimed at documenting their geophysical responses.

Nonsulfide zinc deposits in the Silesia–Cracow district, Southern
Nov 29, 2008The Silesia–Cracow district in Poland has been one of the world’s principal sources of zinc from nonsulfide zinc ore (Polish: galman). The still remaining nonsulfide ore resources can be estimated at 57 Mt at 5.6% Zn and 1.4% Pb. Nonsulfide mineralization is mainly hosted by Lower Muschelkalk (Triassic) limestone and is associated with different

The zinc silicate willemite (Zn2SiO4) is the main carrier of zinc in a number of high-grade, carbonate-hosted nonsulfide deposits located in the southern hemisphere that have been recently reinterpreted to be of hypogene–hydrothermal origin. The timing of willemite mineralization in these deposits is only poorly constrained.
