Abstract. This study compares select dust sampling apparatuses and monitoring methods by investigating fugitive tailings dust transport and deposition at an abandoned Zn-Pb-Cu-Au-Ag mine located in eastern, Canada. The sampling apparatuses and monitoring methods are compared in terms of capturing seasonal trends and spatial extent, as well as ...
Sampling is a technique, based on the assumption that, by and large, every sample has almost the same characteristics of the complete data it is representing. Sampling means the selection and verification of a portion of accounting entries and records out of total similar data. It provides reasonable basis to the Auditor to conclude about the ...
Column expts. revealed that only . 0.1% of vanadium in the soil and mine tailing was leachable. The vanadium concns. in the soil leachates did not vary considerably, but decreased with the leachate vol. in the mine tailing leachates. This suggests that there was a smaller pool of leachable vanadium in the mine tailings compared to that in the soil.
Pyrite (FeS2) and dolomite (CaMg (CO3)2) are the main mineral phases within the sieved tailings, while Zn, Pb, Cu are hosted in a variety of minerals, most notably sphalerite (ZnS), secondary cerussite (PbCO3) and chalcopyrite (CuFeS2) (Cleaver et al. 2021). Based on field observations, there are 3 main tailings types.

First Samples. 6-inch Sampling. In placer mining, there are fundamentally two kinds of sampling: 1) Discovery: Attempting to locate a higher-grade deposit of value inside of a larger volume of lower-grade material. 2) Quantification: Extracting and analyzing smaller portions, to gain a perception of how much value exists within a larger volume.
Sampling tailings can be a tricky operation, as tailings are usually quite soft and can have a low weight bearing capacity. They also are almost always located in annoyingly far flung places. They also are almost always located in annoyingly far flung places.
Tails samples (or mill material balance) from when mill was running may tell you tails total tonnes and grades. How deep, wet and fluid are tails now? This in critical in determining how to sample. (Dry and shallow a backhoe pit MAY work, Dry and deep auger or RC drilling MAY work.).Wet and fluid is more difficult.
What We Do. Phoenix Tailings is founded with the mission to leverage untapped value within mining and refining waste, economically and sustainably.

Sampling. In addition to traditional geotechnical samplers, ConeTec has designed several specialty sampling systems specific to mine tailings applications. These samplers are designed to collect representative samples in tailings materials ranging from process water, to fluid slimes, to liquefiable sandy silt, to dense beach and dyke deposits.
Reprocessing Tailings Dams – A systematic characterisation approach (Part 2) In the first part of this blog ( 2nd April 2014) a brief introduction was given on having a systematic approach to tailings characterisation. There is no argument that tailings dam reprocessing can be profitable, and this blog is not about the methodology to do the ...
Augite occurs chiefly as short, thick, prismatic crystals with a square or octagonal cross section and sometimes as large, cleavable masses. It occurs in a solid-solution series in which diopside and hedenbergite are the end-members. Augite is common in silica-poor rocks and various other dark-colored igneous rocks, as well as igneous rocks of ...

Augite is a rock-forming mineral that commonly occurs in mafic and intermediate igneous rocks such as basalt, gabbro, andesite, and diorite. It is found in these rocks throughout the world, wherever they occur. Augite is also found in …
Augite is very dark green to black in color. The diagnostic feature of any pyroxene is two cleavages that intersect at 89° or 91°. Unlike the feldspars or hornblende, pyroxenes show mediocre cleavages that are hard to spot. Augite is most easily confused with hornblende. Hornblende has highly reflective cleavages whereas augite cleavages are ...

Augite is isomorphous with the minerals Diopside and Hedenbergite.It is an intermediary member between these minerals, forming a series, but contains additional sodium and aluminum within its chemical structure. Strictly speaking, because of the variables in its chemical structure, Augite is really more of a group then a single mineral, but it is still classified a single mineral …
An ideal chromatography peak is a nice sharp symmetrical shape, a Gaussian peak, on a flat baseline. A peak can deviate from this ideal in several different ways. It can become asymmetrical, flatten and become broader, or the baseline can rise. One of the common shifts away from a Gaussian peak is when the back half of the peak falls away.
