Ground BFS is used as an admixture in concrete or as an additive in the manufacture process of Portland slag
cements in countries where large amounts of BFS is available.
, since in this way it would be possible to decrease the incubation times and consequently to increase the thickness of the crystalline layer.
The application of steel slag
from steel mills was not very popular until the late 1990s, for there were vast amounts of blast-furnace steel slag
available, while the steel slag
from steel mills was used for the manufacture of chemical fertilizers, where only the so-called Thomas steel slag
, a by-product of steel production from phosphorous raw iron, was used.
The free oxygen ion may form in metallurgical slags
which are an integral part of the gas-slag
-metal ternary system, as a result of the exchange reactions or in the slag
, between the slag
components with the metal and gas that are in contact with these component.
from a lead blast furnace (the "Lead Blast Furnace Slag
Stockpile") and from a
Possibilities of utilization of waste slags
from niobium production.
1, 2) of interpolated curves for slag
components are used equation between empiric moments and theoretic moments (Girone 2003).
The objectives of this study were to evaluate the effectiveness of these slag
materials with the size characteristics provided at raising soil pH for acid mine soil remediation, and to note the uptake of metals when slags
were used compared to CaC[O.
Results from two of the three laboratories clearly show that the majority of the precious metals extracted are not contained in the buttons; instead, although exhibiting a wide variation, higher values were found to reside in residual parting acid solutions or in the residual slag
that remains following formation of the button.
Calcium Magnesium Aluminate Flux additions to steel ladle slags
allow a quick formation of a homogeneous liquid metallurgical slag
with a high initial MgO-content.
In this stage, during melting of the consumable electrode, the slag
and metal pools travel upwards along the ends of the nipples.
Itronics Metallurgical has been able to obtain nearly complete gold recovery from the slags
