Phosphogypsum (PG) is a massive industrial solid waste. In this paper, PG was purified by flotation method, and α-hemihydrate gypsum (α-HH) was prepared by the autoclaving method. The morphology...
In this work, a hydrothermal-aging pretreatment process is proposed for FGD gypsum raw materials. FGD gypsum is firstly hydrothermally converted to α-CSH whiskers.
In this study, five different pretreatment methods were proposed for comparative analysis to examine the pretreatment effect on the mechanical and environmental behaviors of …
To promote the application of PG, it is crucial to understand how pretreatment affects the properties of hemihydrate phosphogypsum (HPG). In this research, the mechanical properties and microstructure of HPG after pretreatment was investigated for improving the reuse of PG as a promising resource.
Water washing pretreatment significantly reduced the impurities content in the bleeding water and the leachates of backfill. Eventually, almost of PO 4 3−, more than 99.3% of F − and SO ...
This paper studied effect of different pretreatment process on Yunnan phosphorus building gypsum strength and crystal morphology such as washing method, lime neutralization method, flotation method and Hans method.

PG pretreatment with oxalic acid can be utilized in the building gypsum industry. In China, the amount of phosphogypsum (PG) accumulated has been increasing rapidly with the …
In this work, a hydrothermal-aging pretreatment process is proposed for FGD gypsum raw materials. FGD gypsum is firstly hydrothermally converted to α-CSH whiskers.
To address this issue fundamentally, we proposed an effective pretreatment process for seawater desalination using an ion–ion selective nanofiltration (NF) membrane.
PG pretreatment with oxalic acid can be utilized in the building gypsum industry. In China, the amount of phosphogypsum (PG) accumulated has been increasing rapidly with the development of the phosphate fertilizer industry.
In this study, five different pretreatment methods were proposed for comparative analysis to examine the pretreatment effect on the mechanical and environmental behaviors of ternary phosphogypsum (PG), ground granulated blast …
This shows that pretreatment with titanium gypsum can reduce the use of TG in cement retarders instead of natural gypsum or DG, which greatly enhances the resource utilization of titanium gypsum. Currently, DG, PG, TG, …
