Talc in the liver is highly suggestive of intravenous drug abuse. We report three patients in whom finding talc or talc granuloma on liver biopsy led to the diagnosis of unsuspected i.v. drug abuse. There follows a discussion of the pathogenesis, laboratory and clinical features, and liver pathology of talc liver.

AbstractA 45 year old man presented with talc retinopathy that had been present for decades. The static nature of this condition indicates that, in the absence of ongoing intravenous drug use, ophthalmological follow up is not ...

ABSTRACT We present five case reports of the clinical manifestations of talc retinopathy. Photographs illustrate the typical intravascular location of these crystalline deposits which are evident only after repeated injections of street drugs.

Influence of Talc Morphology on the Mechanical Properties of Talc Filled Polypropylene [PDF]
Journal of Polymer Research, 2013 Injected polypropylene (PP)/talc composites were studied to evaluate the influence of different talc morphologies on their final mechanical properties. Talc genesis is responsible for type and content of associated minerals, crystalline degree, particle ...

Twenty-three patients had bilateral intraretinal talc microemboli, which were seen on ophthalmoscopic examination. Twelve of these patients had additional retinal vascular or choroidal abnormalities in the posterior pole that were confirmed by fluorescein angiography.

Effect of aluminum ions on the adsorption of carboxymethyl cellulose onto talc
Minerals Engineering, 2021Talc is a gangue mineral of many sulfide minerals, which is naturally hydrophobic. The depression of talc is very important and challenging in sulfide ore flotation. This research introduced aluminum ions into the process of using carboxymethyl cellulose

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.

Study on the depression mechanism of zinc sulfate on talc in chalcopyrite flotation
, 2021Zinc sulfate is a commonly used selective depressant for zinc sulfide minerals, and a mixture of ZnSO4 and Na2CO3 is an effective combined inhibitor for talc. This study indicated that only using ZnSO4 could inhibit talc in chalcopyrite flotation and its
