Title: Treatment of copper sulfide concentrates
Inventor: DUYVESTEYN WILLEM C
IPC: C22B15/00
Filed: 1992-07-16
Granted: 1993-10-28
Abstract: A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state. The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10 DEG C to 95 DEG C, preferably about 20 DEG C to 40 DEG C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution. The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide. The copper in the leaching solution after further processing is subsequently recovered by electrowinning. The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper. <IMAGE>

Title: Cyclic peptides
Inventor: BENKOVIC STEPHEN J
IPC: C07K7/64
Filed: 1999-12-18
Granted: 2005-05-12
Abstract: Methods of producing cyclic peptides and splicing intermediates of peptides in a looped conformation are disclosed. The methods utilize the trans-splicing ability of split inteins to catalyze cyclization of peptides from a precursor peptide having a target peptide interposed between two portions of a split intein. The interaction of the two portions of the split intein creates a catalytically-active intein and also forces the target peptide into a loop configuration that stabilizes the ester isomer of the amino acid at the junction between one of the intein portions and the target peptide. A heteroatom from the other intein portion then reacts with the ester to form a cyclic ester intermediate. The active intein catalyzes the formation of an aminosuccinimide that liberates a cyclized form of the target peptide, which spontaneously rearranges to form the thermodynamically favored backbone cyclic peptide product. Also disclosed are nucleic acid molecules, polypeptides, methods for making cyclic peptides, methods of making libraries, and methods of screening peptides.

The preferred porosity is provided by pores of the order of 0.05 to 0.01 microns. The coated membrane imparts high resistance to fouling by contact with whole blood, extends the linearity of the electrode response over a substantially greater range, e.g. in the analytical determination of glucose in blood, and combines a high degree of restriction to passage of interferents while retaining high permeability to hydrogen peroxide and oxygen. Most conveniently used for amperometric measurements, especially using a Clark electrode pair, with an "active" anode of platinum.
