Several versions of ceramic bushing/s consisting local heating element/s integrated in apparatus for manufacturing mineral/basalt fibers from natural basalt rocks have been designed based on alternatives to Pt/Pt-Rd bushings approach. The ceramic bushing/s having local heating element/s concept promotes minimization or complete replacement of platinum group metals from the process of continuous basalt fiber manufacturing. More specifically, the invention discloses ceramic bushing/s comprising in combination apparatus are designed for manufacturing continuous mineral (basalt) fibers from 7 to 20 micrometers (&#x3bc;m), and also the coarse fibers from 20 &#x3bc;m to 100 micrometers (&#x3bc;m) in amorphous structural state which exhibit flexible/ductile properties. The minimization or complete replacement of the precious Pt, Rd metals allows reduce the cost of basalt fiber therefore increase its compatibility in reinforced concrete/composite applications including Three Dimension Fiber Reinforced Concrete&#x2014;3D FRC and many other applications. The currently available Pt-Rd orificed bushings are applied for basalt fiber industry greatly limit both the initial raw materials composition, and the efficiency of continuous basalt fiber production increasing their cost. The ceramic bushing/s consisting local heating elements are integrated in apparatus all together capable provide operations from natural basalt rock melting, homogenous basalt glass body preparation, basalt glass body supply to the bushings positioned beneath the bottom platform of the feeder's forehead.
