* DETAILED DESCRIPTION OF WASTE GENERATING PROCESS

Ferrochrome is an essential ingredient for the production of stainless steel, and is an alloy of iron and chromium with a chromium content of between 50 and 55 percent. Stainless steel depends on chrome for its appearance and its resistance to corrosion. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. The ore – an oxide of chromium and iron – is reduced by coal and coke to form an iron-chromium alloy called ferrochrome. The heat for this reaction comes from the electric arc formed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2 800°C. Tapping takes place intermittently. When enough smelted ferrochrome has accumulated in the hearth of the furnace, the tap hole is drilled open and a stream of molten metal and slag flows down a trough into a chill or ladle. The ferrochrome solidifies in large castings, while the slag is separated and stockpiled for further processing.

The product is crushed and screened to exact customer specifications. Alternatively, the ferrochrome is granulated into a flowing stream of water. To improve total ferrochrome recovery while maintaining a high-quality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers and broken down to minus 15mm material. It then moves through a wet jigging plant where the chrome and slag are separated by means of gravity or magnets. The slag is then stockpiled into various size fractions for further use by external customers.

The following factors and criteria must be used to assess the impacts of the activities:

Criteria MAGNITUDE (Severity) DURATION

10 - Very high 5 – Permanent (longer than 10 years) 8 – High 4 - Long-term (5 to 10 years) 6 – Moderate 3 - Medium-term (12 months to 5 years) 4 – Low 2 - Short-term (0 to 12 months) 2 – Minor 1 – Immediate

SCALE PROBABILITY (Likelihood) 5 – International 5 - Definite 4 – National 4 - Highly probable 3 – Regional 3 - Medium probability 2 – Local 2 - Low probability 1 - Site only 1 – Improbable 0 – None 0 – None

Magnitude Magnitude measures the size of the impact

Duration Duration refers to the lifetime of the impact i.e. how long it will last

Scale The scale refers to the extent of the impact.

Probability The probability refers to the chance of impact to occur. The potential impact could be most likely to occur, unlikely, etc.

of 11

Assessment of Significance of impact Significance rating of the potential impacts illustrates the importance of the impact itself. The size of area affected by pollution may be extremely high but the significance of this effect is dependent on the concentration or level of pollution in that area. In order to determine the significance of impact, the following method was used: Significance Points (SP) = (Magnitude + Duration + Scale) x Probability The values of SP are then ranged as follows:

Rating Description

SP >60 Indicates high environmental significance

An impact which could influence the decision about whether or not to proceed with the activities regardless of any possible mitigation.

SP 30 – 60 Indicates moderate environmental significance

An impact or benefit which is sufficiently important to require management and which could have an influence on the decision unless it is mitigated.

SP <30 Indicates low environmental significance

Impacts with little real effect and which will not have an influence on or require modification of the activities.

+ Positive impact An impact that is likely to result in positive consequences/effects

Slag is a heavy and Operator dense material. The potential to cause dust is low. Take precautions to minimize dust formation by wetting of the slag when necessary.

The slag is stable in Operator storage. Slag is usually consumed in large volumes for which packaging is impractical. Avoid deposition outside areas of intended use. Store in demarcated areas. Avoid storage conditions that may generate dust.
