Based on the viewpoint that only if the ground fine ore leaching method is replaced by the extraction from coarse particle ore, the face of uranium ore processing can be changed, this article presents the summary of the studying of thin-layer leaching (TLL) and developing a new process, acid-curing and ferric-trickle leaching (AFL) process (It is called NGJ process in China. ). The operation of AFL process is similar to TLL method, but the water or acidified water is replaced by ferric solution for leaching-rising...

Based on the viewpoint that only if the ground fine ore leaching method is replaced by the extraction from coarse particle ore, the face of uranium ore processing can be changed, this article presents the summary of the studying of thin-layer leaching (TLL) and developing a new process, acid-curing and ferric-trickle leaching (AFL) process (It is called NGJ process in China. ). The operation of AFL process is similar to TLL method, but the water or acidified water is replaced by ferric solution for leaching-rising for cured ore. Ferric-trickle leaching can effectively complete the leaching reaction for uranium mineral in "remaining leaching reaction" that is hardly to be finished in the course of curing. For the most uranium ores in China the AFL-process is competitive with the conventional leaching process. According to this analysis the AFL-process and other extractive processes for coarse particle should become basic extraction process for uranium ore in China. In other words the ore grinding is no more as an essential operation in uranium ore processing in China. Thus, many serious problems caused by ore grinding method in uranium ore processing can be solved and the uranium ore hydrometallurgy will be significantly changed.

根据“要改变铀水冶的面貌,只有用粗粒矿石提取代替磨细矿石浸出”的基本观点,总结评述了旨在改进薄层浸出法,最终发展并形成浓酸熟化-高铁淋滤浸出法(简称NGJ法)的一系列研究。NGJ法的基本单元操作类似于薄层浸出法,只是高铁溶液代替水或酸化水淋浸熟化矿石,从而有效地完成了薄层浸出过程中难以进行的“残余浸出反应”。这样,对中国绝大多数铀矿石而言,NGJ法几乎与常规搅拌浸出法一样有效。由此提出,以NGJ法为基础的铀水冶流程同其他粗粒矿石一起,应该成为中国铀矿加工的基本流程,即矿石的磨细作业不再是中国铀矿加工的必不可少的单元操作。以NGJ法为基础的铀矿加工流程不再存在,由于矿石磨细操作所造成的一系列严重问题,从而根本改变当今铀水冶的面貌。

In this paper,a simple and convenient method of examing gold ore is proposed besides a new concept of reducing type gold ore is established. By this method,a sample of ground ore can be ascertained in the short time of a day whether it is refractory,whether it is necessary to be treated in the presence of acidic medium or alkaline medium and what oxidant should be employed.This paper also suggests that the gold ore which is neither oxidative type nor sulfide type and consumes great quantity of oxidant should...

本文提出了一个简便的检验金矿的方法和还原型金矿的新概念。在拿到磨细矿石后一天内就可判断出这种矿石是易处理矿,还是难处理矿,是需要在酸性介质中处理还是需要在碱性介质中处理,以及选择多大氧化能力的氧化剂。本文建议把那些既不是氧化型金矿又不属硫化型金矿,并能消耗大量氧化剂的金矿石称还原型金矿。并认为要从还原型金矿中提金,首先要使矿石从还原型转变为氧化型。

Bioleaching of NiCu sulfide concentrate with Acidianus brierleyi was investigated in shake flasks. The results confirmed that the most favorable conditions for Ni and Cu simultaneous dissolution were pH 1.2~1.6, inoculum 10%~20%, lower pulp density and the particle size less than 48 靘. Under the condition of 68oC, initial pH 1.6, inoculum 10%, pulp density 5%, Ni and Cu was leached 99.78% and 86.30% respectively after 4.5 d; the dissolution of Ni and Cu could be enhanced by the addition of 50~200 mg/L yeast...
