While the International Monetary Fund projects3 that the MENA region as a whole will see a 4.7 percent decline in economic growth in 2020, Egypts growth rate for the year is expected to remain positive, falling from the previously forecast 5 percent to 2 percent. So while developed economies may face the prospects of a deep recession, Egypt will have to contend with a brake on its upward economic curve that may throw the country off the path of reform and recovery it has been on since the economic devastation that accompanied the Arab Spring in 2011. Just as tourism numbers and growth were recovering after the floatation of the currency in 2018, and a slight increase was seen in foreign direct investment in 2019, COVID-19 has knocked the country off course

Grinding media are either (steel) rods, (steel) balls, or particles of the ore itself. Traditionally, a single stage of roll milling was used before one or two stages of ball milling. The use of ore particles as the grinding medium is called autogenous grinding, and as originally conceived combined all stages of size reduction after primary crushing. Although in its initial uses it was relatively energy inefficient, the lower capital and operating costs saw rapid adoption of the technology. However, many of the early plants experienced difficulties because in practice relatively few ores are suitable for autogenous grinding, because of the buildup in the circuit of intermediate sized (called critical-sized) particles that did not break in the mill. This led to the development of semiautogenous grinding mills (usually referred to as SAG mills). These mills use a small number (about 510% of the mill space) of relatively large steel balls, sized to break the critical-sized particles. (An alternative approach is to remove critical-sized particles from the grinding circuit, and break them in a small crusher.) Some operations have a second stage of autogenous grinding, referred to as pebble milling. This uses medium-sized particles of ore as the grinding medium, extracting them from the preceding primary autogenous or semiautogenous mill. SAG milling has now been developed to a stage where the energy efficiency is equivalent to that of a conventional grinding circuit, and the majority of large concentrators built recently use this form of size reduction. SAG mills, particularly in American practice, have a large diameter-to-length ratio

Particle motion in rotary dryers is one of the greatest challenges in theoretical modeling of dryers (Sherrit et al., 1993). The complex combination of particles being lifted in the flights, sliding and rolling, then falling in spreading cascades through an air stream, and reentering the bed at the bottom, possibly with bouncing and rolling, is very difficult to analyze (Kemp, 2004)
