Metallurgical processing of copper secondary raw materials

Valorization of Phosphorus Secondary Raw Materials by Acidithiobacillus ferrooxidans.

This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L) and two doses (2 and 4 g/L) of phosphorite...

Quality Control of Raw Materials

Food influences the health of a population to a great degree, therefore, the control of food quality is an important government activity, and is legislatively regulated. Raw food materials quality is a complex term that includes nutritional, sensory, hygienictoxicological, and technological points of view. Food has to fulfill all quality requirements, but above all, it has to be safe. High qual...

Horizontal Standardization and Harmonization of Leaching Test Methods for Waste, Secondary Raw Materials, Construction Materials and (contaminated) Soil

In recent years, a lot of work has been carried out in evaluating environmental impact from a wide variety of materials in a wide range of different applications. The continously recurring inability to compare results between different jurisdictions and between disciplines can be resolved by focusing on a limited number of key test methods. This does require the recognition that many existing t...
