Modern analytical techniques and instrumentation make it possible to accurately determine trace mineral concentration in feed and animal tissues. Unfortunately, however, such determinations provide no information on utilization of the minerals by animals. Utilization involves the concept of bioavailability and is critical in the selection of a suitable source of the mineral. In terms of trace m...

Mineral dressing, especially metal minerals in Indonesia, is carried out using appropriate methods based on their properties and characteristics. The method often used gravity concentration. technology that makes use of it a shaking table. This tool works the difference specific pаrtіcle size flowing film concentration which exerts thrust against pаrtіcles deck. In an effort to meet needs pract...

This paper presents a lidar method that enables the determination of quartz concentration in mineral aerosols from simultaneously measured, high-spectralresolution lidar and quartz Raman lidar signals. The method and experimental results are presented.

The concentration of structural hydroxyl groups in the apatite mineral of enamel, dentin and cementum of healthy human teeth was estimated by reference to stoichiometric hydroxyapatite to be 73 +/- 3, 18 +/- 2 and 18 +/- 1%, respectively.
