Solutions to reduce the environmental impact of effluents, wastes and soils affections derived from the metallic mineral extractive activity

Objectives of the commitment

The main objective of the pHMine RMC is the environmental applications of Magnesia products for the stabilization of mining wastes and effluents.
The three specific objectives are the following:
1)- To treat and stabilize mining acid effluents.
2)- To stabilize heavy metals in different natural spaces, avoiding its lixiviation (decreasing the solubility of heavy metals).
3)- To remediate soils ,developing artificial soils for the recovering of altered soils by the mining activity.
4)- To decrease the environmental impact of Magnesite sources at European level, raising the awareness, not only within the EIP community but also to general public acceptance for mining activities.

Description of the activities

A1:State of the Art of the best techniques of environmental applications. T1.1 Studies of the actions to minimise the environmental impact of the mining activity of sulphide ores; T1.2 Study about the CREF of the sulphide ores of the mining effluents; T1.3 Analysis of last Research Projects to keep a Technology Watch on new methods. These tasks consist of the analysis on the state of art of the systems of acid water treatment and contaminated soils derived from mining are currently being used in metal sulfides active exploitations, acidic water treatment system generated in active mines and soils treatments.
A2:Treatment of acid waters. T2.1 Evaluation of the state of the art including the cost-effective passive treatment methods of acid waters; T2.2 Analysis of the implemented an optimized design of a passive treatment of acid mine drainage process and application of a passive treatment of acid mine drainage, for debugging such waters to allow its use for irrigation; T2.3: Development of Pilot plants. The state of the art of passive technologies will be reviewed, including a cost-effective evaluation. Laboratory column experiments. Up-scaling calculations will be done to extrapolate the results to full scale pilot plant. A full-scale passive treatment system will be implemented to treat highly polluted acid mine waters.
A3:Treatment of polluted soils with heavy metals. T3.1 State of the Art of the Magnesium hydroxide to achieve the pH of the soil, where the heavy metals show less solubility; T3.2 Evaluation by using Magnesium hydroxide; T3.3 Pre-treatment for contaminated samples with heavy metals; T3.4 Soil characterization by acid digestion and leaching test. Laboratory scale; T3.4 Chemical analyses for contaminated samples with heavy metals; T3.5 Column Tests for contaminated samples with heavy metals. The objective of the treatment is to stabilize the heavy metals by the generation of insoluble compounds thermodynamic stables, in order that the lixiviates of these stabilized wastes could be released according current legislation.
A4:Treatment of polluted and degraded soils. T4.1 Evaluation of the state-of-the art of soils recovery and degradated habitats due to the extractive activity (mining holes, wastes decantation tanks and tailings); T4.2 Pilot plant. The function of artificial soils in pHMine project is joint economic viable technologies with a satisfactory restoration of soils and with a minimization of future water affections due to mining wastes mobilization (especially heavy metals).
A5:Definition of pilot places and specific measures application. T5.1 Laboratory tests; T5.2 Implementation of solutions in the pilot places. Identification of pilot areas within the mining and processing of metal ores companies, for water treatment, solid and degraded soils. The places will be defined as interest of the participating companies, avoiding any interfering with the normal activity of plants. It seeks to define at least three pilot areas, where defined affections for water, wastes and soil could be treated separately or gathering.
A6:Characterization of materials and laboratory analysis of soils, water and artificial soils T6.1 Soils characterization; T6.2 Water characterization; T6.3 LCA study considering wastes, polluted water and soil affection per ton of extracted sulphide ore or final concentrate. Soils can be characterized by performing different tests by using XRD to identify the atomic and molecular structure of the samples and XRF. Water can be characterized using ionic chromatography and spectrophotometry.

Description of the expected impacts

A1.An analysis of the most suitable systems for treatment of acidic waters and contaminated soils product of mining activity. Lab tests: This methodology assessment will serve for the development of treatment solutions considering the possibility of introducing new neutralizing agents.
A2.An analysis and application of the best passive technology will be done focusing on obtaining water with potential irrigation use. Lab tests. Reports with the results of laboratory column experiments. Full-scale passive treatment pilot system. Results of the passive technology will be published in journals and presented on meetings.
A3.A study of the synergy with other stabilizing agents, mixing the soil with the LG-MgO with reducing agents to treat those metals pH-dependent and also the not pH-dependent one. Lab tests. An evaluation the leachates at lab scale.
A4.A report with a review of current techniques to treat pollited soils. Lab tests. An evaluation of the technologies with a satisfactory restoration of soils.
A5.Pilot places defined and specific measures. Lab tests. Demonstration in pilot areas within the mining and processing of metal ores companies, for water treatment, solid and degraded soils. pHMine will allow the valorisation of a by-product in the prevention, treatment and decontamination of areas affected by Acid Mine Drainage in Sulphide mines, as the Iberian Pyrite Belt, known for it´s geological value, but also for the environmental impacts in historical mining sites as São Domingos, Rio Tinto and other locations.
A6.Characterization tests. Reports with the results of the monitoring of the acid discharge and the treated water will be done; Market study; LCA and LCC analysis of the novel waste management solutions and comparison with those of the benchmark.
