The paper proceeds as follows: Sections 1.1 Basic economic efficiency considerations, 1.2 Phosphate rock mining, industry, and phosphate reserve estimation introduce the reader to basic economic efficiency considerations, followed by a brief overview of PR mining and the global phosphate industry.
The phosphorus utilization from the Gafsa phosphate rock by maize and soybean plants increased when it was applied as compacted triple superphosphate and Gafsa phosphate rock mixture. In the presence of triple superphosphate, the soil-incorporated application of Gafsa phosphate rock led to greater utilization of phosphorus by soybean plants.

India's rock phosphate reserve is estimated at about 260 million t of which only 30 million t are rated as high grade. Beneficiation of low-grade rock being expensive, direct use of ground rock in acid soils is desirable. Partial acidulation of low grade rock is a possible means for minimising P fixation in acid soils. The activity rating of Mussoorie Rock Phosphate is good.
The field experiments were conducted at the Indian Agricultural Research Institute, New Delhi, India for 3 years from 2001–2002 to 2003–2004 to study the relative efficiency of diammonium phosphate (DAP) and Mussoorie rock phosphate along with
2- To boosting the efficiency of rock phosphate as a source of some other nutrients beside P 2O 5. 3- To examine the characteristics (morphology, physico-chemical and phases identification) of the converted nano zeolite for applied in free access uses. 3. Material and Methods
1. Introduction. The efficiency of phosphate mining is directly related to economic and physical losses and can, in more general terms, be expressed as an output–input ratio.
Phosphate rock is the main source of phosphorous which is essential to all forms of life. It is a key component of DNA, it is used in the control of energy transfer and storage at the cellular level as well as playing an important role in metabolic processes.
