With the implementation of policy ecological protection and high-quality development Yellow River Basin, Guohe which is close to middle reaches also an important part future development. Mathematical statistics, Piper diagram, ion proportion coefficient method, Gibbs diagram reverse hydrogeochemical simulation are used analyze chemical characteristics evolution groundwater in Basin (Henan Secti...

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

Tourmaline-bearing quartz veins and replacement deposits, commonly copperand gold-bearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them. Mines and prospects that exploit the tourmaline-bearing deposits are found in a zone approximately 70 miles long and 50 miles w...

The possibility of using a thermomorphic polymer with phosphine group as collecting reagent for the selective concentration tin during flotation enrichment sulfide-tin tails was first investigated in work. A detailed description experimental scheme ore tailings and mode are given. main mineral is cassiterite, highly brittle inclined to sludging, which leads large losses tails; granulometric com...

Abstract Mantle plume rich in gold is considered to be important for the formation of giant epigenetic deposits. The Youjiang basin, SW China, world’s second largest Carlin-type province, but ultimate source its remains enigmatic. In this study, we report that Middle–Late Permian basaltic rocks basin are native grains. These grains scattered interstices pyrite and marcasite amorphous silica cav...

The cassiterite–sulfide mineralization occurs within quartz veins and greisenized Precambrian Older Granite around the Gindi Akwati region at Ropp complex’s western boundary, north-central Nigeria. intrusion of Jurassic Younger granite porphyry sheared marginal parts mylonitized zone created pathways for fluids that escaped during late-stage consolidation biotite granite. granites are highly di...

In this paper, the production process management system of minerals processing is established to realize the optimization of the production indices which are inventory of finished ore and capacity of equipment processing. The structure and function of the proposed system are discussed. A multiobjective optimization model is also proposed, and it aims to reduce finished ores inventory and utiliz...

Analyses for columbium in pyrochlore ores from North Bay, Ontario, have been made successfully by using o-ray fluorescence techniques. rt was necessary to use, as in methods of optical spectroscopy) an internal standard for this work. The choice of a suitable internal standard for a particular metal in a specific mineral association or ore-t).pe requires consideration of the characteristic r-ra...
