Waste utilization has nowadays become more important. Mineral processing techniques have been used in remediation of shooting range soils. The studied soil originated from a Finnish shooting range. This was heavily contaminated by lead-containing pellets and their disintegrated fine-grained weathering products.Using remediation technology based on mineral processing methods the pellets could be separated as a abnormal high grade concentrate containing 97 % lead.The feed materials of the remediation tests were very high lead content having samples the other 14,4 % lead the one 30,9 % lead. Earlier developed separation technology produced high lead recoveries for both test materials 84 % and 94 % respectively.The altering process, which is very commonly known especially for lead and its different compounds, has been moved from original lead into secondary compounds. These compounds are normally very finely disseminated and absorbed especially into organic matter. This phenomen is causing that a part of lead is lost when organic matter is rejected. The lost lead can be recovered by burning the organic matter and separating it from the ash. This gives also an envirommentally friendly total process.
