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 anionic flotation using oleic acid collector to get rougher phosphate concentrate. It was cleaned once using additional quantity of reagents. In the second part, the fines generated during grinding operation were floated by column flotation to recover phosphate values. The cleaned concentrate and column concentrate were mixed together and washed thoroughly with hot water to remove the attached reagents. The final part comprises of cationic flotation of combined phosphate concentrate with fatty amine collector to float away quartz and silicates and to leave behind phosphate values. The grade of final phosphate concentrate was found to be 32.85% P205 with an overall recovery of 88.14%. The concentrate obtained meets the specifications of fertilizer and acid grade.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"120 1","pages":"101-111"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87930834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatments were analyzed physio-chemically and sensory for a total period of 90 days. The statistical results revealed that treatment have a significant (P<0.05) on physio-chemical and sensory attributes of jam. The physio- chemical study revealed that pH, ascorbic acid and non-reducing sugar decreased significantly, while TSS, reducing sugar and % acidity showed a significant increased during 90 days of storage. In sensory attributes, the control and test samples showed a significant difference in texture, taste and colour. The sensory results indicated that with decreased in the apple pulp the texture properties decreases and the opacity increased. The statistical results showed treatment T1(200:200) was found best among the other treatments followed by T2 (250:150) in chemical and sensory attributes.

Two levels of K+ and Ca++ (5 and 10 mM) each were tested on two maize genotypes (Pioneer-3335 and Syngenta-8441) under 100 mM NaCl stress. Saline treatment adversely affected the plant physiological parameters and disturbed the ionic balance and resulted in poor plant growth. However, Syngenta-8441 was more prone to salt stress as compared to Pioneer-3335. Both of the inorganic ions showed significant effects on physiological and ionic components of both genotypes. Among the inorganic ions K was found to be more efficient than Ca in improving the plant growth. Improved physiological and ionic traits were observed more significant with 10 mM K ion treatment followed by 5 mM K. Among Ca treatments higher level of Ca (10 mM) showed more significant results as compared to 5mM Ca++. This study revealed that Ca++ and K+ both are compulsory for maintaining the crop growth because of their mutual effects under salt stress. However, the alleviative efficiency of K is far better than Calcium but its (Ca++) role could not be neglected, while regarding genotypic differential response imposes the fact that Pioneer-3335 is more tolerant to salinity menace as compared to Syngenta- 8441 but both of the genotypes were significant in their recovery from stress to applied Ca++ and K+.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"120 1","pages":"100-104"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77431761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventy representative groundwater samples were collected during pre-monsoon and post-monsoon seasons for the investigation of physico-chemical variables to understand the groundwater chemistry of the coastal belt. Multivariate statistical techniques were applied to interpret the data to reveal the pollution sources in the groundwater samples. The normalized charge balance index (NCBI) was computed on the data set and the STzand STz+ were analyzed in the collected groundwater samples. Cations were in excess and alkalinity in the aquifer of the study area was balanced by Ca+ + Mg+ ions. The contribution of ions was insignificant for charge balance. Mg+2 and Ca+2 were in huge concentration and alkaline hardness was maintained by the alkaline rocks formation. Majority of the charge was balanced by SO4 -2 and Cl. In groundwater ionic composition is used to categorize it into ionic types of groundwater based on the dissolved cation and anion. The ionic reaction is likely regulated by domestic geological formation. The sample location illustrates NaSO4 -2 and Na+Cl nature of groundwater. The groundwater with NaSO4 and Na+Cldominancy generally shows saline characteristics that make groundwater unfit to use for irrigation and drinking purposes.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"36 1","pages":"130-138"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81290520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
