Abstract
As indicated in the title, this article gives brief statements of investigations of various fundamental and practical factors of the ammonia leaching process for nickel and cobalt ores.
The process was in large scale operation at Nicaro, Cuba, as an emergency measure in World War II.
Descriptions of this plant and its operation have been published but these descriptions mainly covered installation and working scale results, and the present article gives a considerable amount of hitherto unpublished data on various phases of the method, including conditions for ore reduction, leaching, distillation, etc.
Possibilities as to further development and results of tests on ores other than the Cuban laterites are also included.
