Apart from natural zinc deposits, so-called urban mines are becoming increasingly important. The term refers to zinc, which is used today as a roofing material, facade sheet or galvanized layer on steel and is available for recycling after many decades. The recycling of zinc is an efficient use of resources and thus an important supplement to the extraction of zinc from ores. Over four million tons of zinc are extracted from these so-called secondary raw materials every year.

This study employed a purely qualitative field survey research approach, where data was collected majorly through qualitative techniques during the fieldwork that took place in the study area between May and August 2014. Data sources included both primary and secondary data. Primary data was gathered through key tools such as participant observation using an observation guide, in-depth interviews using a checklist of questions, and environmental assessments of various mining sites in Prestea. A random sampling technique was adopted for the selection of the communities and/or respondents for the interviews. Communities such as Bondaye, Himan, Ankobra, Asoampa, Bola Ekyir, Ash Town, Nankaba, Dagaatse Compound and Anfegya were selected for the survey. The secondary data used in this study included a critical review of literature on environmental impacts of mining in Ghana, and a review of relevant laws and regulations currently in force. These also included international treaties and other documents or publications relating to standard international best practices of environmental protection.
When it comes to choosing a location for a business such as organic fertilizer production company, there are key questions you should answer and key factors that must be considered.

Often times, in order to achieve the desired end product characteristics, a range in particle size distribution is desirable. This range in particle sizes helps to create a more cohesive pellet or granule, because smaller particles will fill in the spaces between larger ones. A feedstock with too large a particle size would result in a weak pellet, due to the increased amount of void space between particles in the final pellet. In this case, particle size reduction provides the feedstock with the smaller particle size needed to create a pellet of optimum strength.
Remove the lint trap from the dryer. Scrape off as much of the lint as you can with your hands, then vacuum the trap with the vacuum's hose attachment to remove the rest. If the trap still isn't fully clean, hold it under the faucet and rub the lingering dirt with a soft brush to dislodge it. Allow the trap to dry fully before putting it back in the dryer.
The coal is one of the most important energy sources in the world. The drying of the LRC is very essential to utilize it efficiently. Because the coal has a reactive and a combustible nature, the drying technology and the drying media should be determined carefully. Moreover, drying is an energy-intensive process; thus, the energy source for the drying process should be determined with care. There is not only one correct method to dry a product. There are numerous methods in the drying literature. Therefore, every drying process should be studied separately.
