This paper examines the design of comminution circuits and the issues that impact on comminution circuit efficiency. Circuit efficiency is discussed, principally from the perspective of power efficiency. However, operating efficiency, maintenance efficiency, capital expenditure and return on investment are often the key efficiency factors in project development outweighing power efficiency cons...
Arsenic is one of the heavy metals and nearly all its compounds, especially organic compounds, are toxic. The wide spectrum of diseases caused by this element has led to evaluation of the toxicity of different arsenic species and identification of the major natural and anthropogenic pollution sources of it in the nature. Mining activities are among the main sources of anthropogenic pollution of...
to confirm the side-effects of gold sodium thiomalate (gstm), we carried out a retrospective study examining 102 consecutive patients with rheumatoid arthritis attending the rheumatology unit of hafez hospital, shiraz, iran, in whom gstm was initiated between 1983-1989. only patients with classical or definite ra (ara criteria) we(e included in this study. patients were categorized as having de...
The development of new routes and strategies for nanotechnology applications that only employ green synthesis has inspired investigators to devise natural systems. Among these systems, the synthesis of gold nanoparticles using plant extracts has been actively developed as an alternative, efficient, cost-effective, and environmentally safe method for producing nanoparticles, and this approach is...
Organic light-emitting diodes (OLED) fabricated from all “natural” materials will lead to renewable, sustainable, and potentially inexpensive organic optoelectronics. Achieving this goal will require reimagining all the various aspects of the OLED with natural-based renewable materials. Here, we replace the common substrate, electrode, and hole injection layer in the OLED structure with cellulo...
The present investigation entitled, “Effect of integrated nutrient management on corm and cormels production gladiolus cv. PDKV Gold” was carried out during the years 2018-19 2019-20 at College Agriculture Garden, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.).The experiment laid in Randomized Block Design with three replications thirteen treatments. results revealed that, yield paramet...
This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan province,center of Iran, close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study, first grinding circuit and its performance parameters are evaluated. Laboratory and corrected operating Bond work index subsequently were calcu...
