The influence of the ESR parameters namely the flux composition the melting rate the electric current the type of power supply and the ac frequency on the removal of sulfur is considered.
By measuring over a broad frequency range a classification of the different slag types as well as a discrimination between valuable material and surrounding country rock proved to be possible. The spectral classification into five types depending on the shape of the σ" spectrum provides additional information about the subsurface and
· In contrast to IP measurements measured at only one frequency ( 1 Hz in frequencydomain) or by just considering the total chargeability (in timedomain) the classification into different types (Fig. 9 Fig. 10) offers additional information compared with only the slag grade sections (Fig. 7 Fig. 8). Therefore a discrimination between
202182 · Slag treatment mainly utilizes the difference between the physical properties of ash slag components for crushing sieving impurity removal magnetic separation nonferrous metal sorting precious metal sorting and resource treatment to realize the recycling of valuable metal such as iron copper zinc etc. Slag is mainly from 20 to 25 of the incineration generated after waste
201227 · Using converter slag from a nickelcopper plant tests were carried out in 1990 on a 100 kVA furnace (operated at 30 kW) and on a 200 kVA furnace (operated at 85 kW) at low additions of reductant (in order to minimize the reduction of iron). The slag had a composition of Co Cu 3 Fe total 47 Ni and S 3 . These tests

201597 · solutions are independent of frequency in the range from 5 to 100 kHz. The total resistance was measured as a function of the immersion depth the electrodes and was used to determine the cell constant G from Equation 1. Sample Preparation Approximately 100110 grams of slag sample is required for each electrical conductivity measurement.
201994 · Midfrequency Induction Furnace VS Electric Arc Furnace 1. Refining ability In terms of phosphorus removal sulphur removal and deoxidation. Electric Arc Furnace(EAF) is better than Midfrequency Induction Furnace(IF). IF is cold slag the slag temperature is maintained by the molten steel. EAF is hot slag slag is heated by electric arc the phosphorous and sulphur can be removed by the slag
The maximum slag flow velocities are in the range of m/s. However falling droplet could reach velocities up to m/s. During the melting large droplets were emitted at a frequency of about 3 Hz. Due to the droplet formation and to the slag/metal interface movement the electric current lines are continuously changing.
· slag temperature the slag composition and the electric current frequency. 1 Most industrial ESR processes are running with 50 or 60 Hz of frequency of the applied current. The primary reason to use AC currents is to avoid net electrochemical reactions at the metal/slag interface. However AC current with applied frequency lower than 1 Hz is

Abstract This paper presents basic electric properties of laboratory prepared alkaliactivated composite materials on the basis of finely ground granular high furnace slag to which various quantities of carbon nanotubes (CNT) have been added. Impedance spectroscopy in the frequency range from 40 Hz to 1 MHz was used to measure the specimens.
· The electrical resistivity of alkaliactivated slag composite decreases as the amount of graphite powder and the frequency of the AC source increase however at frequencies over 100 kHz the differences in the resistivities of all tested composites become quite negligible.
