This thesis details a study on the feasibility of obtaining a high-purity humic acid material from North Dakota leonardite which can be used as a graphene-precursor in the preparation of lithium-ion battery cathode materials.
These patents relate to the treatment of humic acid bearing ores, such as leonardite, to form a granular ammonia humate fertilizer. However, in these patents, the complexity of the process to form the humic acid concentrate is such that the end product formed is relatively expensive and the process itself employes expensive and complex machinery.
Obtaining humic acid by extracting the humic acid source with an aqueous solution of sodium hydroxide, commonly known as caustic soda, is known. Humates have, in the past, been dissolved in the extracting solution and separated from insoluble tailings.
In U.S. Pat. No. 3,398,186 to Nelson N. Schwartz, et al, a process of extracting humic acid is disclosed wherein an aqueous solution of a sulfate salt selected from the group consisting of sodium sulfate, potassium sulfate and ammonium sulfate is used as the extracting solution.
A liquid humic acid concentrate and a process for making the same is disclosed in which the humic acid is formed by mixing a humic acid bearing ore in a quantity of water and caustic soda for a specified period of time and continuing to mix to form a liquid product of humic acid. The listed assignees may be inaccurate.
