The scientific group defined osteoporosis based on bone mineral density (BMD). A standardized score, called T-score, comparing BMD to average values for young healthy women is used to define the categories. The categories for diagnosis are: normal (T-score -1.0 and above) low bone mass, referred to as osteopenia (T-score between -1.0 and -2.5)

Ore Sorting Strategies In Mineral Processing

Benefits Of Ore Sorting. Ore sorting can exploit a number of differences to sort particles including colour, density, hardness, radiation, and even electromagnetic properties.
