Increasing the efficiency of phosphate ore processing using flotation method
Authors: Aleksandrova Tatyana , Elbendari Abdalla 
Published: July 2021

The paper presents flotation of two phosphate ore samples of different origin. Statistical analysis was used to study the effect of operating parameters on flotation efficiency. The paper proposes to increase the efficiency of flotation processing of magmatic phosphate ore with a low grade of the valuable component (P2O5 = 10.88 %), containing nepheline and feldspars, by means of direct anionic flotation. Authors present an optimization of anionic flotation using tall oil fatty acids mixed with anionic phospholane as an anionic collector. The effect of adding soda ash to compensate for the influence of calcium cations on technological parameters of P2O5 flotation was examined. The results of studying the flotation of nepheline ore (flotation tailings of magmatic phosphate ore) showed that replacement of phospholane with oxyethylated isotridecanol allowed to obtain a high-quality concentrate. It was estimated that with the addition of Na2CO3 in the amount of 2,000 g/t, a concentrate was obtained with the grade and recovery of phosphorus pentoxide equal to 39.15 and 94.19 %, respectively. The paper proposes to increase the efficiency of flotation processing of sedimentary phosphate ore with a low grade of the valuable component (P2O5 = 22.5 %), containing gypsum and quartz, by means of desliming followed by anionic or cationic reverse flotation. Tall oil fatty acid with anionic phospholane was used as a collector in anionic reverse flotation, and amine was used in cationic reverse flotation. Sodium tripolyphosphate was used as a P2O5 depressant. It was found to be an effective depressant in both anionic and cationic flotation. When analyzing the statistical plan, it was estimated that the maximum grade of the valuable component in the concentrate (P2O5 = 31.23 %) and the recovery to concentrate of 95.22 % were obtained in the chamber product at amine consumption of 950.88 g/t and sodium tripolyphosphate consumption of 500 g/t.
New data on the granite pedestal of the monument to Peter the Great “The Bronze Horseman” in Saint Petersburg
Authors: Bulakh Andrei , Popov Georgii , Yanson Svetlana , Ivanov Mikhail 
Published: July 2021

In order to expand and popularize knowledge about the stone decoration of Saint Petersburg, we present new data on the mineralogy and petrography of the famous Thunder-Stone, the parts of which were the basis for the monument to Peter the Great – the legendary “Bronze Horseman”. In the course of studying geological documentation of the monument's granite base, we examined the mineral composition and internal structure of granite, as well as the fragments of a pegmatite vein and veinlets found in it. 25 single-mineral samples were collected from the available micro-scaled shear fractures within the pedestal surface and studied by electron microscopy, electron probe and X-ray phase analysis. It was established that K-Na feldspar in the granite composition was represented by microcline, whereas micas were represented by annite-siderophyllite and muscovite. Accessory minerals included monazite, xenotime, thorite, zircon, rutile, apatite, fluorite, Ti-, Nb-, Ta-bearing minerals, uranium phosphates. The presence of topaz is characteristic of pegmatites. The revealed structural and textural features of four granite boulders in the monument pedestal, as well as mineralogical and chemical composition of their rock-forming and accessory minerals, showed the similarity of this rock to Precambrian biotite-muscovite granites and topaz-containing pegmatites (stockscheiders) of the late formation phase of the Vyborg rapakivi granite massif. The research results are considered as the basis for further geological and mineralogical study of the Thunder-Stone origin and determining the place of its separation from the primary source.
System of Zakat and Ushr – A Paradigm Shift after Eighteenth Amendment to the Constitution of Pakistan
Authors: Samra Umbreen , Muhammad Saad Siddiqui  
Published: July 2021

Zakat and Ushr are important instruments of the Islamic fiscal system. It is an obligatory practice of Islam aiming to help the society and give the deprived ones a better life and opportunities. The fundamentals of the Zakat and Ushr system are clearly defined by Shariah however, its collection and distribution is the responsibility of the state. In this regard, Zakat and Ushr Ordinance 1980 was implemented in Pakistan. The 18th Constitutional Amendment was notified in the Gazette of Pakistan on April 20, 2010. This amendment has redefined the structural contours of the state through a paradigm shift from a heavily centralized to a predominantly decentralized federation. In this regard ministry of Zakat and Ushr was devolved at the federal level and powers were given to provinces to make legislations regarding the subject. After this change provinces made the respective legislations for Zakat and Ushr. In this article, this provincial legislation is reviewed to find out their harmony with the Income Tax Law and practical steps are suggested to achieve the very purpose of these legislations. These steps will increase the collection of Zakat and Ushr that would be helpful to alleviate the poverty and overcome the financial problems of our masses predominantly from agricultural areas of Pakistan. This paper aims to discuss the role of zakat and Ushr as a mechanism for poverty eradication. For this article, qualitative research methodology is used. The content analysis method is adopted for comparison, quantify and analyze the data. Available data on the subject, both in Shariah and conventional law, has been analyzed in detail.

Consumers return purchases for a variety of reasons. Sometimes they change their minds and do not want an item. Perhaps the purchase cant be used as planned, the color or fit is wrong or the product is defective. Many times there would be no need to return items if the customer shopped carefully and planned ahead. However, even the most efficient shopper will occasionally find it necessary to return a purchase for exchange or replacement.

'Micro-Tina' and 'Micro-Gemma' Miniature Dwarf Tomatoes
Authors: Scott John W. , Harbaugh Brent K. , Baldwin E. A. 
Published: July 2021

'Micro-Tina' is a red-fruited, miniature dwarf tomato (Lycopersicon esculentum Mill.) cultivar of a type similar to 'Micro-Tom' (Scott and Harbaugh, 1989) but with sweeter flavor. 'Micro-Gemma' is a gold-fruited, miniature dwarf with superior flavor to that of 'Micro-Gold' (Scott and Harbaugh, 1995). These companion releases provide tomato cultivars that are genetically smaller (plant, fruit, leaves, and stems) than are normal dwarf cultivars. They can be grown in small pots, on window sills, or in small hanging baskets. They provide a well-proportioned plant ideally suited to commercial growing, shipping, and marketing because of their small size and light weight.

Growing Plums in Florida
Authors: Miller E. P. , Andersen Peter C. , Williamson Jeffrey G. , Ferguson James J. , Bitter J. 
Published: July 2021

Plum production has good potential for commercial growers and homeowners in Florida and other mild winter areas throughout the Gulf coast. However, most seasonal plums on the market are from California and will not perform well enough in Florida to produce fruit. From 1998 to 2001, plum cultivars have been released from the University of Florida's breeding program that adapt to our mild winters and high disease pressures. Because they have cropped reliably and produced high quality fruit, these cultivars are recommended for trial in Florida. The names of all University of Florida plum cultivars begin with the prefix 'Gulf.' These cultivars are Japanese type plums (Prunus salicina Lindl.) and have resistance to plum leaf scald (Xylella fastidiosa) and bacterial spot (Xanthomonas campestris). Fruit size is satisfactory (about 1 1/2 to 2 in. diameter) and fruit quality is good. They ripen in early to late May or about two weeks before California plums.
