Keywords flotation frothers, copper shale, critical coalescence concentration 1. INTRODUCTION Copper-bearing shale, also called European Permian black shale or Kupferschiefier 1, 2 is a part the copper ore currently mined in Poland in the Legnica-Glogow Copper Basin area 3. The shale forms a
Jan 12, 2015 Polands environment ministry says that shale gas is hugely popular but mobilisations against it were impressive and fuelled by claims that damage had already been done.
A sample of black shale fraction of copper ore from the Lubin deposit, Poland, was subjected to pretreatment by different microorganisms to improve the copper recovery during the subsequent flotation. Chemolithotrophic bacteria grown on So and S2O3 2- were used to depress pyrite before flotation by means of ethyl xantate as collector.

carbonaceous copper-bearing shale from the Legnica-Glogow Copper Basin region in SW Poland. It was confirmed that naturally hydrophobic shale, known as Kupferschiefer, can be made floatable by application of short chain amines as frothers. It was also established that the short chain amine chloro-derivatives as well as
Mar 05, 2020 In 2018 KGHM Polska Mied KGHM, the only copper producer in Poland, mined 30.252 million tonnes of ore at 1.49 copper Cu and 48.6 gt silver Ag, comprising 452,000t of Cu and 47.2 million ounces of silver. The amount of copper and silver production decreased by a respective 2.99 and 1.28, compared to 2017.
The copper mineralization appears to lie above a red-bed sequence of quartzose sediments in an overlying sequence of black shale with abundant carbonaceous plant trash Figure 1. The setting is strongly reminiscent of the mineralized zones in the Kupferschiefer copper shale, currently mined by KGHM in Poland. Exploration Concept
process of the two samples is due to various content of copper in them. Fig. 4. Autotrophic bioleaching of black shale samples COLUMN BIOLEACHING The bed permeability is an essential process parameter, in the case of column bioleaching. The particle size distributions of shale
Feb 18, 2019 Polands natural resources include coal, silver, copper, natural gas, lead, salt, sulfur, and amber. The country has abundant mineral reserves. However, it is also dependent on the import of mineral commodities for domestic consumption. Overview of Resources. In terms of world production of mineral resources as of 2010, Poland is

Mar 10, 2021 In 2020, Poland-based KGHM Polska Miedz recorded an increase in copper production of 1 at 709 ktonnes compared to the corresponding period of 2019, due to the higher availability of the main production line in KGHM Polska Miedz S.A. and the processing of a higher volume of ore, of higher copper content and with higher recovery, by Sierra Gorda.
The copper production quantity was 66.9 kt. Silver, gold and lead are obtained there as byproducts. The existing silver reserves of the Lubin mine amount to 17 883 t, while all three mines in Poland have total reserves of almost 70 000 t, which corresponds to a lifetime of approx. 58 years.

Decreasing copper recovery and concentrates grade observed at KGHM concentra-tors particularly at Lubin is a result of increasing concentration of shale fraction in Polish copper ores. Black shale is a lithological fraction exhibiting remarkably ele-vated concentration of base Cu, Ni, Co, Zn and precious metals Ag, Au, PGE with
polimetallic shale middlings of the Lubin Concentrator was revealed. Key words pressure leaching, shale ore, copper INTRODUCTION Pressure hydrometallurgy has an extensive application, particularly in processing of zinc, nickel, and copper sulphides and in pretreatment of refractory gold ores, in which gold is finely dispersed in sulphidic lattice.
PRODUCTION. Copper production increased from 400,000ty in the early 1990s to almost 500,000t in 2001. In 2003, KGHM mined 25.83Mt of ore averaging 1.99 Cu, and processed 1.88Mt of 26.76 Cu concentrates. Electrolytic copper output was 529,616t, crude lead 20,134t, metallic silver 1,223t, dor silver 135t and gold 356kg.
Dec 01, 2008 The main conclusions concerning the process alternatives can be summarized for the principle amples of Bioshale project Lubin and Talvivaara. 3.1 Lubin process options Bioleaching tests showed that the Lubin black shale middlings and concentrate fractions were amenable to bioleaching, with extraction of up to 98 of the copper.
According to the latest data Kubacz and Skorupska, 2007 the content of shale fraction in Lubin copper deposit has already reached 27 and became the major problem in effective ore processing. The content of shale in Polish copper ores has almost doubled within last four years. Almost 64 of all valuable metals and 60 of

Jun 01, 2021 Methodology. Our case study focuses on the copper deposit known as Kupferschiefer German for copper shale , a Permian sedimentary-hosted stratiform copper SSC that is found in central Europe. To perform the analysis we used our new mineral exploration product MEP, as well as our ArcGIS-based risk mapping tool, Exploration Analyst.
Jan 01, 2008 In Poland, the Lubin ore deposit which is currently being exploited belongs to this type of geological formation and evaluation of potentially more efficient and environmentally sensitive processing routes is of strategic importance for the Polish copper industry.
