Abstract:

Experiments were conducted to evaluate the effect of phosphate solubilizing fungi (Aspergillus awamori and Trichoderma viride) in phosphocompost preparation along with low grade rock phosphate. Co-inoculation of phosphate-solubilizing fungi significantly increased the nutrient value of the compost that explores high P-solubilizing potential of A.awamori and T.viride which can be exploited for the solubilization of fixed phosphates thereby enhancing soil fertility and plant growth. Rock phosphate application along with phosphate solubilizing fungi increased 69.2% acid phosphatase and 65% alkali

Abstract:

An incubation study on the dissolution of rock phosphates with soils of different pH, was taken up at Tamil Nadu Agricultural University, Coimbatore. It was concluded from the experiment that the dissolution of Udaipur rock phosphate and Mussorrie rock phosphate were remarkably higher in soils with a pH of 5.8 both at 30 and 60 day of incubation, followed by neutral soil (pH 7.6) and saline soil (pH 8.75).During the initial stage of incubation upto 30 days, the dissolution was found to be higher with Udaipur rock phosphate, whereas at the end of 60 days, Mussoorie rock phosphate recorded highe

Abstract:

The phosphorus industry faces the challenge of developing low-grade phosphate reserves for industrial purposes, requiring technological solutions for enrichment. About 20 million tons of low-grade phosphorites are currently unsuitable for processing. Depleting phosphorite deposits and low phosphorus anhydride levels reduce global demand for domestic ore and necessitate research on enrichment and integrated use. This study aims to conduct a thermodynamic analysis of low-grade phosphate enrichment using acetic acid. Using the HSC Chemistry 9.3 program, developed by Finnish metallurgical company

Abstract:

Phosphate ore is an important raw material for manufacturing phosphorous fertilizers and chemicals. Although most phosphate resources cannot be marketed directly as raw material, including that from the Djebel Onk mine, due to their low P2O5 content and high impurity content. To obtain a quality phosphate concentrate, the enrichment of low-grade phosphate ore is therefore of great necessity. The objective of this research was to explore the use of mixtures consisting of three beige phosphate sub-layers and two black phosphate sub-layers as feed material. The objective of this study was also to

Abstract:

A low-grade siliceous sedimentary phosphate rock assaying 22.05% P205 was upgraded by double float (direct and reverse) technology. The rock contains collophane (carbonate fluorapatite) as the valuable phosphate mineral along with siliceous, carbonaceous and clay minerals. A process was developed which yielded a high-grade phosphate concentrate with improved recovery rate. The developed process consists of three parts. The first part includes wet grinding of ore to liberation point followed by separation of fines (slimes) by cone classifier. The finely ground deslimed ore was floated by direct

Abstract:

Concerns about the long-term sustainability of crop production have arisen due to recent observations of stagnant and/or declining yields. The intensive cultivation of high-yielding crop hybrids/varieties and imbalanced fertilizer use as a result of the green revolution have led to a decline in soil fertility and overall system sustainability in India [1]. In light of the negative impacts of chemical fertilizers and their rising costs, there is growing interest in the use of organic fertilizers as an alternative nutrient source for sustainable agriculture production [2].

Abstract According to literature data, Nickel base alloys are not sufficiently corrosion resistant in chloride bearing SCWO environments. Titanium was proposed several times as a suitable material for the construction of a corrosion resistant reactor. Titanium does not show the required mechanical strength for high temperature high pressure applications and it can only be used to form liners for an SCWO apparatus. Therefore, pressure tubes made of alloy 625 were lined with titanium grade 2. Additionally corrosion tests with coupons made of titanium grades 2, 5, 7, 12 and β-C were performed. Th

Abstract:

In recent years, legislative authorities in the US, Europe and Japan have steadily reduced engine exhaust emissions, i.e., carbon monoxide (CO), hydrocarbons (HC), sulphur, particulate matter (PM) and nitrogen oxides (NOx) to improve air quality. To meet these requirements engine manufacturers have had to make significant design changes and as a consequence new engine lubricant specifications from Industry bodies (ACEA, EMA, JAMA) and individual OEMs have had to be introduced to ensure adequate lubrication of these new engines. This has led to significant changes to heavy-duty diesel engine oi
