Jun 25, 2019· The specific sampling issues involved are far from standard. How does one obtain a reliable figure for mercury and gold content in a typical, say, 10ton tailings stock, in which both elements are very irregularly distributed? In fact, the average tailing concentration is at the ultimate low end of trace levels for both elements.

During the period March 25th to April 4th, 2002 a drill sampling program was completed on the Blackdome Mine tailings facility. The primary objectives were to determine the gold content of the tailings and provide material for metallurgical testing. Sufficient grade and recovery could potentially produce a revenue stream, provide material for

Pyrite Tailing Sampling Pyrite Tailing Sampling

Pyrite Tailing Sampling

The tailings consist of 70% sulfide minerals of pyrite, arsenopyrite, sphalerite galena, chalcopyrite, and tetrahedrite, all of which would oxidize to form acidic mine drainage if allowed to sit in piles open to the atmosphere and oxidizing rainfall.

Keywords: mine tailings, mineralogy, geochemistry, geoenvironmental, Spain 1. Introduction Sulfide ore minerals are generally concentrated by milling and flotation, which produces tailings containing gangue minerals and residual sulfides. Milling involves crushing and grinding to reduce particle size and liberate ore minerals from the rock matrix.

Preliminary studies revealed that the main mineral phases of this southern Chilean tailing are diopside, epidote, chlorite, garnet (andradite), actinolite, calcite, quartz, pyrite, pyrrhotite, sphalerite and magnetite. The sampling of the deposit took place at the "old tailing"district, which has been inactive for about 40 years.
