Similar improvements to the high-temperature chloridizing-reduction-magnetic separation method have been made by Chen et al. (2017), who revealed that the use of 2 wt% CaCl 2, carrying out chloridizing at a temperature of 1398 K for 10 min, and implementing the reduction process at a temperature of 1323 K for 80 min, yielded …

Abstract. Disclosed are a variety of processes for the purification of saline minerals and in particular, trona. Some of the processes include a combination wet and dry recovery process which results in high recovery and purification at relatively low cost.

Trona ore consists mainly of trona, sodium sesquicarbonate dihydrate (Na 2 CO 3 ·NaHCO 3 ·2H 2 O), including minor undesirable insoluble materials. With the present industrial practice, there is no particle separation process to remove these insoluble minerals prior to thermochemical processing. In this current research appropriate …

A process for the beneficiation of trona includes supplying a trona feedstream that is crushed and dried. The trona is then separated into a first size fraction and a second size fraction. Impurities are removed from the first size fraction using at least one magnetic separator. The magnetic separator includes a plurality of stages.

A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21, 22 ].

The trona beds occur with layers of oil shale, marlstone, and sandstone/mudstone. These insoluble contaminants include a number of double carbonate salts in addition to dolomitic shale, quartz and clays (Garrett, 1991).In the industry, there are two commercial processes to remove the insolubles and produce soda ash from the …

The magnetic separation process successfully separates quartz, mica, and other gangue minerals with iron mineral. This is demonstrated in Fig. 13, where the diffraction peaks of hematite weakened and those of magnetite increased through roasting. This indicates that the transformation of hematite to magnetite occurred during roasting.

magnetic gangue minerals are first separated from trona ore by a dry magnetic separation process, followed by the flotation ofthe nonmagnetic trona concentrate. The overall evaluation of this new separation technology for the recovery ofa high-grade trona product is the subject of this paper. Materials and methods

One method of enriching trona involves supplying a feed stream to a crushed and dried trona. The trona is then divided into a first dimensional portion and a second dimensional portion. Impurities are removed from the first dimensional portion using at least one magnetic separator. The magnetic separator covers many stages. Each stage includes …
