s3R has developed the RecCo-Marilyn dry recovery process, described in this brochure, in order to provide the stainless steel industry and its contractors with a complete proposal for the recovery of all valuable stainless steel scrap from residual slag as from 1mm upwards. The rest product is a marketable residual slag fraction of 0-10mm slag, which, after it has been treated with FeSO4, safely converts 3Cr6+ particles into Cr3+ particles, thus creating an environmentally safe end product.

After an initial site visit and some laboratory testing, we will present customers with a basic engineering concept including flow sheet, layout, cross-sections and a CAPEX budget.
The payback of the RecCo-Marilyn concept is 1-2 years.

The first concept for a 75 t/hr, single shift/day recovery plant was sold in 2005 to a Taiwanese customer. This plant will be fully operational in may 2006.

A second order was placed in February 2006 by the largest stainless steel producer in the world, the Chinese company Tisco for a 150 t/hr plant, 2 shifts/day, 760.000 t/year plant.
