copper tailings detection method

A REMOTE SENSING AND GIS METHOD FOR DETECTING

based on three characteristics— the absence of organic material, the homogenous grain size particular to copper mill tailings, and wetness. The research was successful on two points: (1) the detection method functioned on a fixed set of input parameters, and (2) it eliminated all non-tailings features.

Copper Tailing an overview ScienceDirect Topics

As copper tailings appear in ground form, the grading of copper tailings reported by Gupta and Thomas (2013) and Nitish et al. (2013) has a sizeable silt fraction of 0.06–0.002 mm. Copper tailings are considered to be finer than CS, which usually has a dominant sand fraction. Table 6.5 compares the geotechnical properties of copper tailings to those of CS, which have been reported in this

New approaches for extracting and recovering metals from

May 15, 2017· Mineral tailings from two copper mines were bioleached under different conditions. • Greatest copper extraction was achieved at extremely low pH, at 45 °C and under oxidative/reductive conditions.. Copper present in tailings PLS was selectively precipitated as CuS by biogenic H 2 S.. Microbial communities were dominated by Sb. thermosulfidooxidans and Acidithiobacillus spp.

TENORM: Copper Mining and Production Wastes Radiation

Jul 08, 2019· Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined.

CN103157558A Beneficiation method of recovering sulfur

The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings. The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more than 20%, and the concentration

Tailingsfo What Are Tailings? Their nature and production

The engineering characteristics of tailings are in most instances influenced by the degree of thickening and the method of deposition. It is therefore essential that while investigating the properties of tailings that the physical characteristics and material parameters (e.g. beach slope angles, particle size segregation, water recovery) that can occur as a result of varied deposition

Physico-chemical characteristics and heavy metal

Mar 23, 2019· The pollution load index (PLI) was nearly twice higher for the tailings dam (8.97) than the overburden (5.84). The findings show that the copper mine wastes (the tailings dams and overburden waste rock sites) are highly contaminated by heavy metals; which, in turn, might pose serious hazards to human health and agricultural productivity.

Tailing Disposal Methods and Tailings Dam Construction Design

As there is seldom enough ground available on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to save the expense of obtaining a fresh supply

Mount Polley Mine Tailings Dam Failure: Update on

The non-sulphide copper analysis (i.e. a 2.5% sulphuric acid leach) indicated that up to 66% of the solid phase copper in the tailings materials is associated with the non-sulphide portion of the tailings. As extremely acidic conditions are required to leach this form of copper, it is considered
