Salt Slags Processing Operating Costs. The estimated annual operating cost for a plant capable of processing 100 tons per day of salt slag is $1,368,700, as shown in table 9. This corresponds to a cost of $41.48 per ton of slag processed. The estimated operating costs are based on an average 330 days of operation per year over the life of …

The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. It's necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects: • Earthworks • Mechanical

The capital cost analysis at the time of the expansion showed 53,000.00 per ton for the conventional plant and $2,000.00 per ton for the SAG plant. Their operating cost comparison shows a ratio of 100 versus 88.9 for conventional versus SAG. We understand that prior to the plant shutdown in 1977, that the comparison was 100 versus 80.

EAF slag is a rock-like material generated during the steel-making process. Approximately 130 facilities across the United States generate EAF slag. EAF slag is used as an alternative to rock fragments, both in encapsulated uses (e.g., contained in concrete) and unencapsulated uses (e.g., loose ground cover material).
