Phytoextraction of zinc copper nickel and lead from a

Abstract. In a pot culture experiment, five different species of Brassica Brassica juncea, Brassica campestris, Brassica carinata, Brassica napus, and Brassica nigra were grown for screening possible accumulators of heavy metals, viz. Zn, Cu, Ni, and Pb. The plants were grown to maturity in a soil irrigated with sewage effluents for more than two decades in West Delhi, India.

Application of Fly Ash and Slag Generated by Incineration

Application of Fly Ash and Slag Generated by Incineration

Results show that C30 concrete optimum replacement rates of fly ash and slag are 30 and 20, which can meet the minimum strength requirement. The leaching concentrations of Cu, Zn, Pb, Cr, and Cd in MSWI concrete samples are determined to be less than the identification value of

Preparation of Black Ceramic Tiles Using Waste Copper Slag

Preparation of Black Ceramic Tiles Using Waste Copper Slag

Copper slag and stainless steel slag of Electric Arc Furnace EAF are two typical metallurgical solid wastes, which contain a large number of valuables, such as Fe, Cr, and Cu. The transition metal elements in the waste slags, such as Cr and Fe, can be recycled as the coloring ions in the black ceramic tile. In this study, the FeCr molar ratio in the raw materials of copper slag and ...

Shortterm leaching study of heavy metals from LD slag of

Shortterm leaching study of heavy metals from LD slag of

Mar 15, 2016 As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, V and Zn were leached from LD slag from three major steel industries i.e. Roulkela, Bokaro and Tata Steel Plants of India and were analysed by inductively coupled plasma optical emission spectrometer ICP-OES.

Characteristics and environmental aspects of slag A

Characteristics and environmental aspects of slag A

Jun 01, 2015 Zinc slag contains comparable amounts of Ni, Pb, and Zn to Cu slag but the As, Cd, Co, and Cu contents do not reach the maximum values found in Cu slag. Elements that commonly exceed environmental soil screening levels in Zn slag include As, Cr, Pb, and Zn . Nickel sulfide slag contains Co in concentrations that exceed the industrial soil ...

PYROMETALLURGICAL SLAGS AS A POTENTIAL

PYROMETALLURGICAL SLAGS AS A POTENTIAL

Cu from 7,48 to 64,95 , and change in a broad range. This slags show significant heterogeneity, caused by inter-metallic phases Zn - Pb, Cu - Zn, Cu - Pb formed on the surface thereof. It is so possible that slag can be a potential source of this metals recovery.

Characteristics and environmental aspects of slag a review

Characteristics and environmental aspects of slag a review

The concentrations of some elements exceed generic USEPA soil screening levels for human contact based on multiple exposure pathways these elements include Al, Cr, Cu, Fe, Mn, Pb, and Zn based on bulk chemical composition. Each slag type usually contains a specific suite of elements that may be of environmental concern.

An overview of recovery of metals from slags ScienceDirect

An overview of recovery of metals from slags ScienceDirect

Jan 01, 2003 For example, in the leaching of a brass smelting slag containing 6.3 Cu free metal, 14.4 Cu oxide form, 11.35 Zn oxide form and 1.33 Pb oxide form with hydrochloric acid or ammonia, addition of H 2 O 2 greatly increased the extent of metal extraction, especially in the hydrochloric acid leaching, as shown in Fig. 3, Fig. 4 Basir et ...

Blast Furnace Slag Cement an overview ScienceDirect Topics

Blast Furnace Slag Cement an overview ScienceDirect Topics

Test in nitric acid NEN 7345, 1993 Ba, Zn, Pb, Cr and Cd show concentrations below detectable limits. Comparing the different matrices, there is a lower release of Zn and Cr matrices with Portland cement and with blast furnace slag gepolymers, a fact probably related to the high alkalinity of the calcium-containing matrices.

THE EFFECT OF COPPER CONTENT IN THE MATTE ON

THE EFFECT OF COPPER CONTENT IN THE MATTE ON

experiment, samples of slag and matte were gathered in order to determine the contents of Cu, Au, Ag, Pb, Zn, Ni, As, Sb, Se and Bi with the aim to determine their distribution coefficients between these phases. Matte quality, determined by the contents of copper in the matte, ranged from 36.31 Cu to 42.12 Cu, in the investigated system.

Chemical and mineralogical evaluation of slag products

Chemical and mineralogical evaluation of slag products

Slag products from pyrolysismelting plants were sampled for the purpose of detailed phase analysis and characterization of heavy metal-containing phases using optical microscopy, electron probe microanalysis EPMA, XRF and XRD. ... Elevated concentrations of Zn, Cr, Cu, Pb and Ba were recorded in the bulk composition. Cu, Pb and Ba behave as ...
