Cost-Effective Treatment of Hemihydrate Phosphogypsum and Phosphorous Slag as Cemented Paste Backfill Material for Underground Mine
Published 2019-01-01“…The results show that (1) the UCS of CPB increases with the increase of the HPG content and mass fraction, and the addition of 3% quicklime can eliminate CO2, H2S, and SO2 generated from the slurry of CPB-based HPG-PS; (2) the addition of 3% quicklime and 5% cement to the HPG-PS mixtures can offset the strength loss of CPB in the late curing stage; (3) the UCS of the recommended specimen reaches 1.15–3.32 MPa after curing from 7 to 28 days, with their slump values varying from 15 mm to 26 mm, and the bleeding rates between 0.87% and 1.15%, which can meet the technical requirements of mining methods; (4) the UCS of CPB is the result of the cohydration reaction of hemihydrate gypsum (HG) in HPG and active Al2O3 and SiO2 in PS; and (5) the leaching indexes meet Category IV of the Chinese Groundwater Quality Standard (DZ/T 0290-2015). The results of this investigation provide a cost-efficient way for the efficient mining of phosphate resources and the comprehensive utilization of HPG and PS.…”

Impact of Climate Variability on Coffee Production in Kambuga Sub-County Kanungu District.
Published 2024“…The study revealed the impact of climate variability on Coffee Production in Kambuga sub-county, Kanungu district, and these include; climate change as a reason for the rapid spread of leaf rust, hotter temperatures have caused plants to lose several growing days in their usual harvest cycle, coffee plants need a terrain with rich soil, rainfall and temperature changes are likely to reduce yields of desirable crops, temperature increases may cause changes in runoff and groundwater recharge rates. The study showed the practical adaptation strategies to mitigate the negative impacts of climate variability on coffee production in Kambuga sub-county, Kanungu district as they include; shade Management, water management, soil health management, crop diversification, pest and disease management. …”
