Selective separation of chalcopyrite and talc using pullulan as a new depressant
, 2021As a gangue mineral, talc is usually associated with chalcopyrite. Therefore, the depression of talc is required in the field of sulphide mineral flotation.

Flotation separation of chalcopyrite from talc using a new depressant carrageenan
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020As a typical gangue mineral in many sulfide deposits, naturally hydrophobic talc needs to be depressed by adding depressants to achieve a good flotation separation.

Depressive realism and clinical depression
Behaviour Research and Therapy, 2010Depressive realism suggests that depressed individuals make more accurate judgments of control than their nondepressed counterparts. However, most studies demonstrating this phenomenon were conducted in nonclinical samples. In this study, psychiatric patients who met criteria for major depressive disorder underestimated control in a contingent ...

The anionic flotation of fluorite from barite using gelatinized starch as the depressant
, 2020As an important non-metallic mineral widely used in industry, fluorite is normally associate with barite in nature. Anionic flotation is the most efficient method to separate fluorite from barite in mineral processing while the critical point of ...

Depression often presents with physical symptoms, primarily fatigue, pain, or sleep disturbance. Depressed mood may or may not be present. Supportive counseling and pharmacotherapy are more effective than either modality alone. The newer drugs are better tolerated than earlier agents, and they achieve much greater patient adherence.

Selective flotation of Cu-Mo sulfides using xanthan gum as a novel depressant
, 2020Molybdenite and chalcopyrite is generally separated through the selective depression of chalcopyrite using potentially toxic depressants such as sodium sulfide and cyanides.
