The number of their workers represents only 0.23% of the number of workers in other factories, and the invested capital represents only 0.08% of the invested capital in the rest of the factories. [108]  Industrial projects in the region are mostly individual projects with limited funding. all of them are national in the absence of foreign investment. Most industrial activity is limited to the food and beverage industry, depending on wealth and potential in the region. [108]   The Ministry of Petroleum and Mineral Resources (now called the Ministry of Energy, Industry and Mineral Resources) has conducted exploratory and prospecting studies for the region. Consequently, the presence of many raw materials was determined, such as: clay in the areas of Jal Ajrabeh and Al Dhailiya, which is used in the manufacture of building materials. Silica sand is found in the areas of Al-Malih and Al-Luja and on the extension of the Tabuk road, southeast Sakaka. Silica is used in the manufacture of glass, and it exists in its forms of quartz, opal, and chalcedony. [109]  In the region, there are also basalt rocks found in Hurra Al Hurra, and enter in the manufacture of Pozzolan cement. The region also contains limestone rocks found in Wadi Al Hablah and western Jabal Al Abd, dolomite rocks along the Sakaka Arar road, the mineral phosphate found in Hurra Al Hurra, and salt found in Wadi Al-Sarhan, Hadhodhaa, Kaf, and Etherh. [109]   In the past, trade in the region depended on the system of bartering and the exchange of goods according to the needs of the individual. The region suffered in the year 1356 AH (1937 AD) and until the year 1365 AH (1945 AD) for two reasons, namely the lack of imports due to the weak financial resources of the population, and the Second World Warthat caused an economic crisis to a number of countries in the world.
