Agglomeration and leaching of slimes and other finely divided ores. [John D Sullivan; Alfred P Towne]. b / agglomeration and leaching of slimes and other finely divided ores, $ 20 b / permissible methane detectors, $ 10 b / permissible electric mine lamps, $ 10 b / refining of light petroleum distillates, $ 20 b / agglutinating, coking, and by-product tests of coals from pierce county, washington, $ The paper describes the development of a method of stabilizing agglomerated slimes by the formation of a cementing substance in the glomerules.

The conclusions based upon agglomeration tests were as follows: The porosity and permeability of finely ground ores can be greatly increased by moisture agglomeration.

These ores are the original material from which high grade Mesabi hematites have been evolved by natural leaching and oxidation.

The recoverable iron mineral is finely disseminated magnetite and the ore must be ground to about 80 % of size – mesh for liberation, the concentrate containing about 65 % iron and 8 % silica. Other researchers have applied and developed knowledge on the leaching of various gold ores, including an effective resin-in-leach (RIL) and elution process (this is described in more detail in Chapter 50).

Much of the work has focused on understanding and applying the copper-catalyzed ammoniacal thiosulfate system to carbonaceous ores and Cited by: October ; Revised, June MC/ History "From tothe U.S.

Radium Corporation was located at the intersection of High and Alden Streets in Orange, New Jersey. Sabin Arnold von Sochocky and Dr. George S. Willis founded the company in The primary activity at the U.S.

Radium Corporation was the extraction and purification of radium from carnotite. Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years.

Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations. The drum agglomeration is considered as a pretreatment step for the heap leaching of copper and gold ores whereas the agglomeration of uranium and nickel ores has Cited by: Magnetic separation and leaching process are useful to work on hematite ore.

Similarly flocculation process is also deliberate for extraction of ultra fine iron particles from slime in secondary. Gooden et al. () reported phosphorus was not removed from an Australian ore from the Pilbara in a caustic or acid leach.

However, Fisher-White et al. () were able to remove some phosphorus from an Australian Brockman Iron Formation ore sample by leaching with sodium hydroxide or sulfuric acid as shown in Table Leaching Brockman ores containing % and % P with 20% NaOH Cited by: 1.

Also, as has been found in applications of the MNR process (Section ), the wide range of ionic species that are produced in the cyanidation process and which are precipitated during the sulfide-precipitation stage, can result in extremely finely divided slimes that are almost impossible to by: Agglomeration and leaching of slimes and other finely divided ores / C Ventilation of the large copper mines of Arizona / Factors governing the entry of solutions into ores during leaching.

The handbook provides a single source for understanding how aqueous solvents or mineralizers work under temperature and pressure to dissolve and recrystallize normally insoluble materials.

The presence of slimes is, in general, harmful to the flotation of iron ores, affecting the selectivity and the quality of the concentrates, besides causing an increase in reagents consumption.

This work describes the behavior of different iron ore types from the Iron Quadrangle, Brazil, with respect to desliming in hydrocyclones and flotation, including a study on the dispersion degree as a.

A method of leaching ores comprising finely dividing the material, agglomerating the fines with the larger particles thereof, placing the mixture of agglomerates in a leaching vessel, depositing a layer of large particles of relatively hard material thereon, and gently discharging the leaching solution onto the layer of relatively hard particles at such a rate that a continuous leaching film is provided in the mass.

The adverse effects of slime coating, by which a value mineral is covered by slimes and prevented from direct contact with collectors.

The Leach Vessel (See Fig. 16) This vessel has a capacity of cubic metres. It is fitted with an air sparge and an air operated agitator that has two sets of blades, one set located near the bottom of the vessel and the other midway in the optimum charge.

The vessel is also fitted with baffles and the floor is sloped .Read more. The method of the invention consists of wetting the crushed ore, or other finely divided feed material, with an alkaline cyanide solution considerably more concentrated than that conventionally employed, allowing the wetted ore to age for a time sufficient for agglomeration of fines in the ore and for substantially complete reaction of the cyanide with gold or silver, and then leaching soluble gold or silver cyanides from the aged ore.

The conclusions based upon agglomeration tests were as follows: The porosity and permeability of finely ground ores can be greatly increased by moisture agglomeration. Variations in the amount of solution used in agglomeration causes a noticeable difference in the amount of permeability.

The maximum permeability is reached between 10 and 18%. You searched for: different slime. Etsy is the home to thousands of handmade, vintage, and one-of-a-kind products and gifts related to your search.

Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present.

Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than. Start studying Slime. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
