Some Fundamental Aspects of Dry Slag Granulation Process

Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of slag into a saleable

production cost, due to heat recovery from slag cooling and elimination of drying step. 5 References [1] M. Yoshinaga, K. Fujii, T. Shigematsu, and T. Nakata: "Dry Granulation and Solidification of

Gold Recovery : 8 Steps (with Pictures) - Instructables

Cupellation is simple weigh the solid pieces of low grade gold, burn the crap out of it until you get no more slag and it becomes a nice bright yellow bead, and then you weigh it after it cools. My solid low grade gold parts with garbage attached went from 180 grains to 75.9 grains of high grade gold with no garbage attached.

Experimental investigation on granulation characteristics

In essence, gas quenching slag granulation process is a gas-liquid flow atomization process which includes primary breakup and secondary breakup .In the primary breakup, the growth of Kelvin Helmholtz (KH) unstable wave at the gas-liquid interface causes the film to break up into ligaments .The size of ligaments is related to the wavelength (λ KH) and film thickness (h).


This paper deals with formation of slag in smelt-ing process, its chemical composition, physical and st ructural characteristics, utilization and product speci-fications as well as environmental aspects. The slag products are standardized and CE marked. Additionally the role of slag in smelting and alloy recovery is reviewed in this paper. 1.

Slag Atomising Technology: Unlocking Real Value

This slag treatment method reduces dust creation and water consumption, and also allows for energy recovery from the molten material. Through innovative process designs, slag is now intrinsically valuable as a raw material for a number of other applications e.g. sand blasting, ballast, or roof shingles.

Dry slag granulation with integrated heat recovery

CSIRO has been working on the dry granulation process since 2002 and has made major breakthroughs in novel process design. The work has recently been extended to include heat recovery from the slag, in collaboration with industrial sponsors (BlueScope Steel and OneSteel as part of the Australian Steel Industry CO2 Breakthrough Program).


method. In addition to the recovery of valuable metals, the slag product of the process, known as Plasmarok®, can be sold for use as an aggregate, owing to its inertness, low leachability and engineering properties. The exhaust gases pass into a secondary combustion chamber to oxidize species such as organic

slag granulation description - LighthouseChristengemeente

PROCESS AND INSTALLATION FOR GRANULATING SLAG. In a process for granulating slag, from a blast furnace or a smelting reduction plant, in which a granule/water mixture formed during the granulation is fed to a granulation tank and then to a dewatering installation, in which the slag granules are dewatered.

Process for the recovery of gold using plasma - Tetronics

The gold concentrate thus obtained represents less than 5% of the mass of the original refractory gold containing concentrate and contains about 98% of the available gold. The process of the present invention may also be used for the recovery of gold

Cutting-Edge By-Product Recycling for Iron- & Steelmaking

Dry slag granulation with heat recovery. Primetals Technologies, voestalpine Stahl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an R&D program to develop a new dry-granulation technology using air to cool molten slag and recover the lost heat energy.

A Poor Man's Method of Smelting Gold | Sciencing

May 22, · Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass — which will have floated to the top during the cooling process — and there is your gold, smelted to perfection.

What Are Commonly Used Gold Recovery Chemicals? | CNFREE

In gold cyanidation leaching process like CIL, CIP process, the commonly used gold recovery chemicals are sodium cyanide and eco-friendly gold dressing agent. Of course, it’s necessary to choose the suitable gold recovery chemical for the gold recovery plant according to the properties of the gold ore itself, the project condition and

Hatch Ironmaking Technologies | Dry Slag Granulation

Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.
