A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook

Bachelors Theses and Reports, 1928 - 1970

The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.

A Study Of The Effect Of Temperature Upon Reactions Between Stannous And Arsenate Ions In Silicic Acid Gels, Ellis Elder

University of the Pacific Theses and Dissertations

Chapter I: Statement of the Problem

The purpose of this investigation was to determine to what extent the reaction between stannous and arsenate ions in silicic acid gels is influenced by temperature.

This was to be done by observing (1) the rate of crystal growth; and (2) the appearance of the crystal growth in sets of gels identical in composition but kept at different temperatures throughout the process of crystal growth.

The Development Of Colloid Chemistry, Oscar A. Bouise

Electronic Theses and Dissertations

At first, it was as a blur, that had shrouded a great mystery for ages and ages, until some seventy odd years ago. Then came Thomas Graham, who could not satisfy himself with merely viewing a blur as a blur. Being a scientist, he applied his mind experimentally, which the keen precision of any of the eminent astronomers using a telescope, and viewed more clearly this mist which hovered above the horizon.

Anhydrous Alcohol And The Vapor Phase Method Of Preparing It, Cleetis Brown

University of the Pacific Theses and Dissertations

Since the almost universal laboratory method of preparing absolute alcohol requires considerable time and trouble, gives a low yield of alcohol and leaves a distilling flask badly clogged with hydrated lime, Professor S.S, Kistler and I undertook the following research in the hope that we might devise a new method that would be both rapid and easy to perform.

Upon reviewing the possibilities, it seemed evident that any method to be rapid would have to involve drying In the vapor phase. Diffusion in a liquid being so slow that when a drying agent is placed in the liquid phase an …
