What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfiderich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created threatening to

Self Potential Anomalies and their Minerological

It was observed that the potential anomalies are due to some conductive minerals like graphite and sulphide ore bodies. The Isopotential contour map of the study area was made with an interval of 50mV which reveals the mineralogical trend of sulphide and graphite ore bodies.

AUVCSEM An Improvement in the Efficiency of MultiSensor

Seafloor massive sulfide (SMS) deposits are of interest because of their potential as copper and gold orebodies. This mineralization is often highly conductive, and consequently, electromagnetic mapping of these deposits for ranking of drilling targets often follows autonomous underwater vehicle (AUV) surveys that include multibeam bathymetry, side scan sonar, and chemical sensor data collection.

MASSIVE SULPHIDE DEPOSITS Earth Sci

The average massive sulphide camp in Canada has about 9 deposits, but ranges from four (Manitowadge) to 21 (Noranda), However, an individual deposit may consist of a number of closely associated, discrete lenses ranging from several thousand to several million tons in size (ea. Millenbach Mine was 16 geologically discrete ore

Seafloor massive sulfide deposits

Seafloor massive sulfide deposits

Seafloor massive sulfide deposits or SMS deposits, are modern equivalents of ancient volcanogenic massive sulfide ore deposits or VMS deposits. The term has been coined by mineral explorers to differentiate the modern deposit from the ancient. SMS deposits were first recognized during the exploration of the deep oceans and the mid ocean ridge spreading centers in the early 1960s.

Jun 30, 2018· The marine selfpotential (SP) method is used to explore for hydrothermal venting and associated seafloor mineralization. Measurements are commonly made in deep water using instruments towed close to the seafloor, which requires dedicated ship time, is to slow speeds, and is subject to navigation errors. Massive sulfide ores of the

The variograms of the ore distributions are characterized by hole effect, trend and zonal anisotropy, which reflect alternation of ores with host rocks and changes in elemental contents. The Siirt Madenköy deposit is attributable to Cu and Zn ratios of the Cu class of ophiolitic massive sulfide deposits.

The electrochemical mechanism of sulfide selfpotentials

Abstract. Selfpotentials associated with a sulfide ore body result from the ohmic potential drop within the country rocks. The electric current is produced by separate but simultaneous reduction of oxidizing agents near the surface and oxidation of reducing agents at depth. The ore does not participate directly in either reaction, but serves as a conductor to transfer the electrons from the reducing agents to the oxidizing agents.

Sulfide ore bodies have been sought by the self potential generated by ore bodies acting as batteries. Other occurrences produce spontaneous potentials, which may be mapped to determine the information about the subsurface. Spontaneous potentials can be produced by mineralization differences, electrochemical action, geothermal activity, and
