This paper studies the influence of two pH modifiers, namely sodium hydroxide (NaOH) and sodium carbonate (Na2C03), on the flotation of celestite ore using sodium oleate as the collector and sodium silicate (Na2SiO 3) as the depressant. The use of Na2CO 3 provides the best results for the concentration of celestite, under the same experimental conditions. © 1998 Elsevier Science Ltd. All rights...

in this work attempts were made to evaluate k+-sds and hydrocolloid polymer-sds interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. different dispersions of micronized megestrol acetate and sds were prepared. kcl and kh2po4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

A field survey was carried out to increase knowledge on salts produced from plants in the west of Ivory Coast. This work intends serve as a basis for real promotion "plant salts" food additive domestic and industrial production. It would also like provide an alternative severe low-sodium diets. is Coast, salty products made used substitute sodium chloride. These "edible plant are differentiated...

In this study, polyvinyl chloride (PVC) was pyrolyzed with sodium hydroxide (NaOH) to capture the generated hydrogen (HCl) gas as (NaCl) and carbonize organic contents generate fuel gases such (H2) methane (CH4). addition, pyrolysis behavior of PVC NaOH, its application copper recovery from thin PVC-coated tinned multiwire cables were examined. With an increase in temperature, released HCl at a...
